The fact that Google launched a 7" tablet by ASUS isn't a particularly huge surprise, given that ASUS showed off the Eee Pad Memo back at CES. The story goes that Google liked that particular tablet so much, it became slotted in to become the first Nexus tablet, much to Samsung's chagrin. While there have been other "Google Experience" tablets before (for example the Motorola Xoom), there hasn't been a bona-fide Nexus tablet yet, and especially not one at an aggressive price point like this. For that, enter the Nexus 7.

The Nexus 7 comes with Android 4.1 Jelly Bean installed, which we're going over on the next page. It brings improvements to UI performance through Android 

Most important is the Nexus 7's price point, which up until now has largely been one of the main issues with Android tablets - price. It's fair to say that the Kindle Fire has done a good job proving that there is indeed a market for lower cost, simplified tablets at an aggressive price point, and the Nexus 7 is Google's answer. Pricing for the Nexus 7 is $199 for the 8 GB model, and $249 for the 16 GB model. There aren't any other differences between the two, nor is there a model with cellular connectivity – this is strictly WiFi only, but again, this is a tablet for the masses without the carrier hurdle.

When you look at the above specs, it seems puzzling that ASUS was able to get the price down to $199 so effectively. Getting to that lower price point is easier with a few things - physically smaller device and display, exclusion of full size USB or other ports (there's only microUSB), no rear facing camera, and good commodity component sourcing. The added plus is that if you run 1280 x 800 at a smaller size, out comes a pretty high DPI panel at the same time. Other than that though, you end up getting a device which is actually very impressive otherwise, with a quad core SoC and attractive form factor.

I like starting with physical impressions since it's the easy route, and so much of one's experience with a given device depends on that ever important in-hand feel. ASUS has taken an excellent direction here and made the back construction of the Nexus 7 a great textured rubber material. There's Nexus embossed in the top, and ASUS proudly at the bottom. Below that is a small notch for the speaker, which goes pretty loud. 

The power / lock and standby buttons get placed on the top right corner, and both microUSB and the headphone jack are located at the very bottom. There are also some pogo pins on the bottom left, just like the Galaxy Nexus. No doubt these will work with some future unannounced accessories.

The Nexus 7's construction is downright impressive. While I haven't been doing regular tablet reviews (that has become Anand's domain largely), I have handled a number of recent tablets big and small, and some feel downright cheap to me thanks to the back plastic. I would not have guessed that the Nexus 7 is a $199 device based on how it feels. There's no flex or creaking at all, it feels absolutely rigid. The tradeoff is that the Nexus 7 is slightly thicker than some other devices, at almost 10.5 mm (compared to 8.5 or 9), but that larger thickness also permits a bigger edge bevel radius. I feel that 7" is an ideal tablet form factor for me personally. 

So the next logical question is what performance is like on the Nexus 7. I asked around, did my own digging, and wound up confirming that what's inside the Nexus 7 is indeed a Tegra T30L SoC. This is a lower leakage / lower binning T30 that no doubt is offered at a cost advantage to ASUS - I was expecting a T30L inside and am wholly unsurprised to see one. The only difference is that CPU clocks are 1.15 GHz for all four cores at 100%, or 1.3 GHz on a single core. The GPU clock is also slightly lower at 416 MHz. The Nexus 7 also ships with 1 GB of RAM, and I'm pretty certain this is DDR2 at 500 MHz based on what I see from the digging I've done. 

I've borrowed Anand's TF700T review graphs and added data from the Nexus 7 that I hastily ran this afternoon. The results are in line with my expectations for T30L and other devices with T30L inside that we've already benchmarked.

GLBenchmark 2.1 - Pro (Standard)

The Transformer Pad 300 uses the same T30L SoC as the Nexus 7, so it isn't surprising to see the two post numbers very close to each other in so many places. 

I should note on the browser synthetics that we're also talking about Chrome here, not "Browser" as the Nexus 7 is the first Android device to ship with Chrome as the default browser. In this case, that means there's no "browser" to be found anywhere on the device. You can still install Flash from the Play Store, it just doesn't do anything anymore.

Speaking of digging, I sent Francois Simond (@supercurio) a voodoo report from the Nexus 7, and he has graciously done a component analysis just like we've done with other devices in the past. There aren't too many surprises inside. WiFi and Bluetooth is courtesy the ever-ubiquitous BCM4330 module, which no doubt has gotten cheaper now that BCM4334 is out. The front facing camera is a Aptina MI 1040 1.3MP CMOS with 3.6µm pixels and 1/3" optical format. NFC comes courtesy a new NXP PN65 controller which is best I can tell a PN544 with embedded SE (secure element). 

The next question is what that display looks like. We've seen other lower cost tablets ship before, but usually the first thing that gets skimped on is the display. In the case of the Nexus 7, ASUS notes that the panel is an LED backlit IPS panel with 10 point multitouch and 400 nits maximum brightness. Resolution is of course WXGA (1280 x 800) at 7". If you do the math out, that's a pretty high PPI, and in person it looks great - I can't see pixels unless I look very closely. 

Pixel Density Comparison

Since I expected having to do something of a tablet review on this trip to Google I/O, I brought along my i1D2 colorimeter. I took measurements on the Nexus 7 using my normal workflow – a combination of Francois' Voodoo Screen Test Patterns and Color HCFR. 

Display Brightness

Display Brightness

Display Contrast

Brightness falls a bit short of the advertised 400 nits at just 312 nits. I'm actually not sure whether there's some of Nvidia's Prism power saving tech going on here (there's no toggle anywhere for it), but that's as bright as I could get the Nexus 7 to go. Contrast on the other hand is pretty good, at 850, and blacks are very good at 0.37 nits. 

The rest of the display metrics are a bit interesting, with color temperature hovering around 5500K which is a bit warm for my taste, and gamma isn't flat over the grey scale either. What's really curious to me is that the greens seem undersaturated (the larger triangle is sRGB), which was my first impression on seeing the Nexus 7 while installing some apps from Google Play (which has lots of green). Again I'm not sure whether this is some power saving Prism technique at work here. 

I feel like those metrics could mislead you into thinking the display is bad, on the contrary it's obvious this is an IPS panel based on the viewing angles, which are superb off axis in the horizontal and vertical. You just can't get away with putting a TN in a tablet because of how bad viewing angles are immediately visible on a big surface device like a tablet. The Nexus 7's IPS display is very contrasty and has a high enough PPI that I'm not wishing for higher resolution.

Google is also doing something interesting with the Nexus 7 by bundling a $25 Play Store credit which pops up in your account after signing into your Google account for the first time. The strategy seems pretty obvious here - get Nexus 7 buyers to at least check out the Play stores. In addition, they've preloaded a number of books and videos which should bait users into at least checking out the respective Google Play applications. 

Honestly I think ASUS and Google have really done an excellent job here with the Nexus 7. The combination of a quad core SoC, IPS panel, solid construction, and the latest version of Android all for such a killer price point pretty much make it hard to really find any faults. Sure, it'd be useful to have a full size USB host port, microSD slot (though no Nexus has shipped with one since Nexus S), 5 GHz WiFi (Nexus 7 is 2.4 GHz only), or cellular, but the tablet wouldn't be $199 anymore. I also really feel like the 7 inch diagonal form factor is an ideal one, and the Nexus 7 is quickly growing on me.

Update: I've had many emails and questions about whether USB-OTG (On The Go) is supported on the Nexus 7, and didn't touch on it when I originally hit publish becuause I wasn't entirely sure. I've now confirmed that USB-OTG is supported on the Nexus 7, and works on the current Android 4.1 non-final build that has been sampled. That's encouraging, and I'll test it myself when I get home and to my miniUSB OTG adapter.

Update 2: I've asked for further clarification about what USB-OTG functionality is supported. Using a mouse and keyboard will be supported, and I saw Google using an ethernet to USB adapter over USB-OTG as well. Unfortunately I found out that mounting USB storage will not be supported natively. In addition MHL is not supported.

Now, what about Android 4.1?

    Why should I want to squash down my DVDs? I just go, buy a Galaxy Tab with a Micro SD slot and have enough storage not to have to convert my files into a bad quality. And because of that, I critizize the Google Nexus 7. It doesnt have enough storage, so they lose me as a buyer and its their own fault.
    By now, its not a Problem to have 100GB on a Tablet, this is the modern technology we have by now. Its the fault of the manufacturers to not use the modern technology and losing consumers who know what they can get today, what todays state of the art storagespace is. 128GB is state of the art and not 8GB or 16GB. This was way back in 2008.

    You are all in luck. In fact Amazon sells a little adapter only 1 inch high that inserts into the mini USB power port. It then on the bottom gives you 4 ports. 1 power port 1 Full SD 1 Full USB 1 Micro SD. Cost 20 bucks on Amazon. Reply

    Try looking there for some cheap gadgets like microSD readers and other nifty gadgets. That's why my previous comment about using the MicroUSB with a MicroSD reader, why the big deal?

    Deal Extreme is a HK company but ships for free, though takes a bit longer, from about 2-3 weeks so you have to be patient and I've ordered from them many times just for cables, adapters, card readers and other small gadgets that aren't very expensive, though sometimes quality of items can be iffy.

    "Local storage should be nothing more than cache."

    Great idea, as long as you trust Google with your data (I don't).

    I don't understand why anyone would be willing to store anything of importance on a cloud service. The few advantages are outweighed by some pretty major disadvantages.

    If we do that, we should just remove Storage from all Desktop and Notebook PCs. But this will not happen. Why? Because the cloud is inferior and slow compared to local storage. And I hate it to download everything again, again, again and again just because some people think its "cool" to do that and force everyone to use the cloud by removing local storage.
    The cloud is just a made up hype. It is good for emails and textfiles, but not for 1080p Videos and Music. Its a pain in the ass to have to download everything again JUST because there is not enough storage to save your files on your device.

    I understand the disappointment, but I think a lot of people don't realize USB OTG is a decent compromise. If you really want extra storage for music/movies just take a thumb drive and a 2" USB OTG cable with you when traveling... It'll mount just like a PC, you can even get cables with a right angled microUSB male connector so that the short cable is parallel/flush with the tablet and exerts less torque on the port (less danger of yanking on it while holding it).
