Google’s Nexus One Costs $174.15 [Google]

Google Nexus One Carries $174.15 Materials Cost, iSuppli Teardown Reveals El Segundo, Calif., January 8, 2010-With its new Nexus One, Google Inc. has taken many of the latest smart-phone innovations and combined them in a single product that manages to be both cutting edge and cost competitive, according to a teardown conducted by iSuppli Corp.

The Nexus One, sold with the Google brand name but manufactured by HTC Corp., carries a Bill Of Materials (BOM) of $174.15, based on a preliminary estimate from iSuppli's Teardown Analysis Team. This total comprises only hardware and component costs for the Nexus One itself and does not take into consideration other expenses such as manufacturing, software, box contents, accessories and royalties.

Google Nexus One Carries $174.15 Materials Cost, iSuppli Teardown Reveals

El Segundo, Calif., January 8, 2010-With its new Nexus One, Google Inc. has taken many of the latest smart-phone innovations and combined them in a single product that manages to be both cutting edge and cost competitive, according to a teardown conducted by iSuppli Corp.

The Nexus One, sold with the Google brand name but manufactured by HTC Corp., carries a Bill Of Materials (BOM) of $174.15, based on a preliminary estimate from iSuppli's Teardown Analysis Team. This total comprises only hardware and component costs for the Nexus One itself and does not take into consideration other expenses such as manufacturing, software, box contents, accessories and royalties.

Google is selling unlocked versions of the Nexus One at an unsubsidized price of $529, or at $179 with a two-year service contract from T-Mobile.

"With the Nexus One, Google has taken the most advanced features seen in recent smart phone designs and wrapped them up into a single sleek design," said Kevin Keller, senior analyst, competitive analysis, for iSuppli. "Items like the durable unibody construction, the blazingly fast Snapdragon baseband processor and the bright and sharp Active-Matrix Organic Light Emitting Diode (AM-OLED) display all have been seen in previous phones, but never before combined into a single design. This gives the Nexus One the most advanced features of any smart phone ever dissected by iSuppli's Teardown Analysis Service-a remarkable feat given the product's BOM is similar to comparable products introduced during the past year."

The attached table presents the preliminary results of iSuppli's teardown analysis of the Nexus One. iSuppli will conduct a finalized and more detailed analysis later this month.

Return of the Snapdragon

At the heart of the Nexus One is Qualcomm Inc.'s Snapdragon baseband processor that sports a blistering 1GHz clock speed.

"The Snapdragon was first noted in a previous smart phone torn down by iSuppli-the Toshiba Corp. TGO1-which is based on Microsoft Corp.'s Windows Mobile operating system," Keller said. "However, the Android 2.1 operating system used in the Nexus One better capitalizes on the Snapdragon's fast performance, making the user interface and applications run very quickly.

This processing muscle also gives the Nexus One some advanced capabilities, most notably high-definition 720p video playback."

iSuppli estimates the cost of the Snapdragon at $30.50, making it the most expensive single component in the Nexus One. With the inclusion of the Snapdragon and the associated power-management and Radio Frequency (RF) transceiver chips, Qualcomm commands 20.4 percent of the Nexus One's BOM, giving it the biggest dollar share of any component supplier in the design.

AM-OLED display

One of the Nexus One's signature features is its 3.7-inch AM-OLED display, which is superior to the conventional LCDs used in most smart phone designs in a variety of ways. Compared to LCDs, AM-OLEDs deliver a larger color gamut, a faster response time, a thinner form factor and reduced power consumption.

Prior to the Nexus One, AM-OLED technology appeared in another smart phone, Samsung's I7500, which features a 3.2-inch display. However, the Nexus One uses a larger display, marking the first use of a 3.7-inch OLED that iSuppli's Teardown Analysis Service has seen.

"The 3.7-inch AM-OLED display on the Nexus One delivers a stunning picture," Keller said.

With an estimated cost of $23.70, the AM-OLED display is supplied by Samsung Mobile Display Co Ltd.

Heavenly unibody

The Nexus One also sports a unibody design, which means that the smart phone's enclosure comprises a single part. Such a design approach provides greater structural rigidity, providing more protection to the internal electronics in case the phone is dropped. On the other hand, a unibody tends to drive up manufacturing costs.

Besides Apple Inc.'s iPhone, this marks the first unibody smart-phone design that iSuppli's teardown analysis team has noted.

With the Nexus One, HTC has taken a major cue from Apple in the enclosure design, making it the most "Apple-like" product yet seen from any in the competition, and others are likely to follow suit.

Noises off

The Nexus One also features a dual microphone design used for cancellation of background noise. This feature also was noted in Motorola's Droid, another Android-based smart phone. To implement the noise cancellation function, the Nexus One employs a specialized audio voice processor chip from Audience Semiconductor, the first time iSuppli's Teardown Analysis service has observed a part from this manufacturer in any electronic product.

Lost memories

The Nexus One includes a large quantity of DRAM, employing 4Gbit (512MByte) of Samsung Semiconductor's Double Data Rate (DDR) DRAM. This compares to 1Gbit or 2Gbit for comparable smart phones. The large quantity of DRAM is required to store executable code to support the fast performance of the Snapdragon processor, and allows for better application performance.

While the Nexus One features 4Gbit of internal NAND flash memory, the same amount as the Droid and the Toshiba TG01, it is bundled with a comparatively small MicroSD card of 4Gbyte. NAND flash is used for storage of user content and media on the smart phone. The Droid and TG01 are supplied with 16Gbyte and 8Gbyte, respectively. This allows Google to keep its overall BOM costs down, yet still allows the user to upgrade as needed. And while the 4Gbyte of internal flash pales against the iPhone's whopping 16Gbyte, it has the advantage of expandability afforded by the MicroSD card slot where the iPhone has no external storage facility.

Samsung Semiconductor is the supplier of all the memory in the Nexus One, giving it $20.40, or 11.7 percent, of the product's total BOM.

Synaptics gets in touch

Other notable design winners in the Nexus One include Synaptics Inc., which supplies the phone's capacitive touch-screen assembly. iSuppli estimates the cost of the assembly at $17.50, or 10 percent of the total BOM. While the module and the Android operating system support multitouch input, the capability is deactivated on the Nexus One.



Happy Moments at CES [Ces2010]

Through the photonic assault, I saw a patch of green in a booth. I walked up and touched it. The grass, it was real, and cool and fresh for the moment. I could not have smiled more broadly. Happy Moments...

...at CES are rare for attendees, in my experience. It's hard work and a monumental commercial achievement at the expense of sanity, holiday vacations and sleep. But these moments of joy do exist.


Dell showed a 5 inch Android tablet. It's too small to be more useful than a smartphone, and can't be pocketed as easily, but for some reason, I found it sexy. And that one of the most mainstream makers of PCs made something so cool, well, I was impressed. I'm not sure I would buy one, but it made me happy.


I miss my dogs. They're being watched in Japan for the month by Lisa's parents, and I'm going back to pick them up in a week. They're black and brown, and these mascots also happen to be black and brown. I guess they reminded me of my pets without me realizing it, and I decided to give them a hug. Cozy.


I made fun of 3D HDTV a lot. Then I tried it on a really good set with fast refresh rates, by Panasonic. I loved it and to me the difference between 2D and 3D is as profound as the difference between black and white and color TV. I got excited at the thought of playing games and watching movies with lots of explosions and lush scenery (Planet Earth, HD!) with a third dimension.


Another great moment of happiness came when I felt we were hitting our stride, as a team, covering the show. No trailer, no booth, no place to set up and write in peace. But since we were all here, together, I was able to ask everyone how they were doing without typing it. It's nice to communicate without a keyboard, once in awhile.

We bought pizza for ourselves and since the lunches were cold, got some for our pals in the press room.

Seeing the Gizmodo junior team learn so much so fast has been inspiring. I got especially happy watching Don and Kyle nail their shorts and Rosa, well, Rosa found the best story of the show. And the veterans are just so good, they're always surprising me with astounding finds and speed of insightful writing.

I bumped into a lot of friends here, not only those I work at Gizmodo with. Chris Null, Sean Captain, Leander Kahney, Charlie White, Dylan Tweeney, Joe Brown, Steve Leckart, Danny Dumas, Ryan Block, Veronica Belmont and Pete Rojas, naming a few. And this is actually the first time I've worked side by side with Joel Johnson, who returned to Giz only last month.

In a few hours, this show will be largely done for us. Everyone who worked on the blog will have a nice dinner together. Then I'll go home. That will be my most happy moment.

*We noticed these people were having a good time at CES, too. If you look closely, most of them have to do with people interacting with each other, not the machinery.

Touch Revolution Nimble Landline Phone: Android For Office Drones [Android]

Android in washing machines! Android in tablets! Android in... a desk phone? If you're still plugged into a landline all day at work, you next phone might just run Google's smartphone OS.

To say that the Touch Revolution Nimble just runs Android is a bit of an understatement, because it actually runs on an extremely thorough custom interface designed by The Astonishing Tribe, the firm that conceived the original Android UI. The result makes me very, very jealous. Or at least it would, if I ever used a traditional phone for anything, which I don't, because I'm under the age of 35, and I have a strange job on the internet. Anyway! Here's how it works:

You'll probably never see the Nimble as the Nimble again, since this is a reference design to be sold to phone manufacturers and resold under a different brand. And you'll probably never get to buy one, because they'll be marketed as enterprise devices, not consumer phones. But who cares! CES is all about gawking at stuff you'll never buy, in case you haven't noticed.

MSI Projector PC Beams Those All-Important Word Documents Out At 1080p Resolution [Computers]

MSI took the humble projector and added the guts of a PC, making—are you ready for this?—THE PROJECTOR PC. Connect it to a keyboard, chuck in a mouse, and beam your Excel on your dog. Or whatever.

In terms of ports, it has a HDMI out, LAN, 4x USB, 3.5mm headphone jack, mic-in, and even a DVD slot on the front. Internally, it's rocking an NVIDIA ION graphics chip, along with an Intel Atom processor, and in terms of video, it projects 1080p onto a 60-inch diagonal. The contrast ratio is 1000:1, and the lamp brightness is 100 lumens. It's not as bright as a SIM2 special obviously, but MSI explained it's somewhere between a pico projector and a home projector.

It's just a concept for now, but MSI was pretty confident they'll be able to get it to market in the third quarter of 2010. Look out for it then, if projecting Word documents is your usual style. [MSI]



Take Typeface Personality Quiz, Experience Self-Discovery [Typefaces]

I normally bristle at personality quizzes for their asinine generalizations and overall lameness. But I have to respect the creativity of this video test that Fast Company discovered. Helvetica nerds, this is for you.

After entering your name and the password (character), the video proctor asks you a series of four questions that you click to answer on the left. Afterwards, it diagnoses your personality type, likens you to a typeface, and gives you a brief history of your kindred font. Neat. [Pentagram via Fast Company]



Notion Ink Adam Pixel Qi Tablet/Ereader Hands On: Your Screen Is Obsolete [Tablets]

Housed in a wooden, painted prototype case, the Notion Ink Adam tablet is rough. But with Pixel Qi dual-mode screen tech on one arm and Nvidia's Tegra 2 on the other, it's one of the most exciting devices at CES.

We've seen a fair share of Android 2.0 tablets at CES, some of which share not only Android 2.0 with the Adam, but the Nvidia Tegra 2 processor, too. But what they don't have is a Pixel QI transflective screen, a 10.1-inch panel that can switch between backlit LCD mode and low-power electrophoretic reflective mode, which looks more less like E Ink, and which actually gets easier to see in direct sunlight.

We got our first good look at this screen tech this morning, and we covered its weaknesses: the LCD colors aren't as vivid as a plain LCD's and suffers at some viewing angles, and the reflective mode suffers from the glossy screen's glare, but in both modes, it's good enough. (And Notion honcho Rohan Shravan says he's working on a fix for the latter issue.) What this means is that no matter what you're using the device for—browsing the web over 3G, reading an ebook, watching a video—you can switch between screen modes depending on your environment or preference.

As I said before, the device is still in development, so you're seeing protoype hardware (there's prospective second model with a curvier exterior, too), untouched software (Rohan promises a custom interface, with a solution for text input other than the awkwardly sized standard keyboard), and unoptimized performance (Android 2.1 should help the interface move a little more quickly). We'll get a fuller picture of the device come Mobile World Congress in February, as well as pricing info—though we're assured we'll be "very happy" about it.

Anyway, you can stack these caveats as high as you want, and the Notion Ink Adam is still taller, if just for this reason:

We repeat: The bullet's in the chamber. E Ink is going to die.
