I bought my Nexus 10 after my mother stole my Nexus 7 from me and I'm sure glad she did. My girlfriend had just gotten an iPad 4 for Nursing School so I had something to compare it with.

Let me say the screen is the pinnacle for tablets by far, just watch the planet earth HD episode that comes with. The pixel density is much better than the iPad but not as saturated, which is fine with me because it looks fake. The speakers set it apart from any tablet in terms of loudness and the fact they are front facing so you don't have to look like an idiot cupping the back of your tablet for people to hear. The camera is surprisingly good; auto focuses and takes photos very fast. Skype looks better on here than my laptop, not to mention its nice to use the back camera for a video tour, concert, etc. Its extremely fast with no hiccups that I've noticed (in 3 months). Frequent updates which is rare for a Android device. Coming from the Tegra 3 quad core processor on the Nexus 7, the dual core A15 1.9Ghz and Mali GPU on the 10 plays games just as well which is impressive for the best screen in tablets. Movies don't get any better. The absolute best video experience in tablets, I guarantee. As an engineering student, this device has been more than capable and helped me be organized and prepared for classes.

Reasons why I like my Nexus 10 over my girlfriend's iPad 4:
-better screen
-front facing speakers
-better multi-tasking
-more customization
-can open zips
-can download attachments from sites that the iPad can
-can use flash
-can plug in any USB accessories with OTG cable (flash drive, mouse, keyboard, xbox controller) without installing anything or paying for over priced device specific accessories

*iOS does have more tablet optimized apps but that's the OS and not the device itself. This tablet is hardware superior in every way and the OS is much more capable.

Before beginning this review, here are products that I own that I have used for comparison (most of which I have reviewed on this site): the ASUS Transformer TF300 T-B1-BL 10.1-Inch 32 GB Tablet (Blue) with the matching ASUS Transformer Pad Mobile Dock TF300T (Blue), the Apple iPad MC705LL/A (16GB, Wi-Fi, Black) 3rd Generation, the Asus Google Nexus 7 Tablet (8 GB) - Quad-core Tegra 3 Processor, Android 4.1,Windows RT Surface 32 GB Tablet, the HP TouchPad Wi-Fi 32 GB 9.7-Inch Tablet Computer, and the venerable Samsung Galaxy Tab 10.1. I love mobile devices, and have plenty of experience with Android, iOS, Windows RT, and webOS devices. Now for the review.

PROS
+ Dazzlingly sharp screen. If you're looking at the Nexus 10, you've likely seen this specification front and center. The resolution handily beats that of Apple's third and fourth generation iPads, but in practice it's hard to see the improvement. That's not because the Nexus 10's screen isn't an improvement-- if you look, it's there, and reading web pages is truly a joy-- but after a certain point, you really run into diminishing returns.
+ Rich content experience. While you do hit some diminishing returns, the Nexus 10 has quickly become one of my favorite tablets for content consumption, whether that's watching video or reading books. While both the newer iPads and this tablet (and really, a number of other excellent Android options, like the ASUS TF700T-B1-CG 10.1-Inch Tablet (Champagne)) now come with 1080p or better screens, Android tablets tend to have the edge when it comes to YouTube and video content due to their 16:9 aspect ratios (although they all do quite well, really). The Nexus 10's screen helps make web and text reading great, which is important considering many find the 16:9 ratio awkward for such tasks (more below).
+ Sleek, svelte build out of great materials. The backing is soft-touch and ever-so-slightly rubberized, and while not quite as easy to grip as a Nexus 7, the device sticks in the hand. Perhaps more importantly, it has a nice, warm feeling to it-- one complaint I've had about all-metal tablets like the iPads and premium Transformer Pads is that holding cold metal in your hand feels premium, but often uncomfortable. There's zero flex in the chassis anywhere, nothing creaks, and the slim, trim profile looks great. I personally think it looks friendlier than an iPad, but I will note that if you're fond of angular and straight-edged designs, the Nexus 10's pronounced curves may throw you. On the other hand, it's thin and light, and comfortable in the hand.

Oh, and branding is minimal. Most of the required stuff is under a neat little panel that snaps off to let you attach cases and keyboards and such (although said accessories are noticeably missing at this time-- someone dropped the ball on this one).
+ Excellent performance. Performance is really determined by both the hardware and the software, and for now, I'll look at the hardware. Powered by a new chip of the A15 "Eagle" variety, Samsung's Exynos 5250 destroys basically every Android tablet chipset out on the market (note I am not including the Snapdragon S4 Pro, as it's not really available on tablets yet outside of Qualcomm's reference build). Zero lag, zero stutter, fast and snappy graphics playback, and fluid gameplay (but take this last with caution: while every review I've seen has praised its gaming ability, I myself play relatively simple games like Steambirds or Anomaly: HD). Sometimes the tablet will run a little warm, but none of this lap/hand burning people complain about so much these days.
+ Android 4.2 under the hood. Android's come a long, long way in recent years, and even if you're a dedicated Apple user, you should at least look at Google's latest offering with an open mind. Stock Android has morphed from (what I believe! Important caveat!) a gaudy, neo-futuristic mess (Gingerbread) into a sleek, industrial, polished, and smooth system (beginning with Ice Cream Sandwich). In more recent releases, the OS has become far more understated visually, serving only to help you navigate your apps and content and getting out of your way besides. Android 4.2 has released several new features of interest to most buyers, but I'll look at two in particular. The first is multi-user support: now, you can have one tablet service multiple users, with a tap on the lockscreen switching between them. That means a "family" tablet can also hold your personal work e-mail, with no fear of other family members accessing your data. The second is a quick settings toggle. Android OEMs have long built in Wi-Fi/GPS/Bluetooth and other switches into their devices, but until recently you would need an app like Power Toggles to replicate the same on a stock Android device. While Google's implementation of settings toggles leaves a little to be desired, at least the functionality is there (unlike a certain fruit-named brand-- seriously Apple, all I want to do is toggle Wi-Fi. Do I really have to jailbreak for that?!)
+ Great connectivity. You get a micro-HDMI out port and micro-USB, and it's the latter that really opens up the device's capabilities. Buy a cheap USB OTG cable from Amazon (you can get them for south of $2 with free shipping if you look), and hey presto, your Nexus 10 can work with USB keyboards, mice, and with a little tinkering, flash drives. Good way to solve the limited storage issue (see below).
+ Sound sound sound. Taking cues from Samsung's Galaxy Tab 2 10.1 and Galaxy Tab 10.1N designs, the speakers are now on the front panel of the device. The stereo set pushes out quite a good bit of clear, loud, audible sound. For a tablet, the only device I've seen that comes remotely close is the HP Touchpad. But as with all things, keep in mind that the device is ultimately a tablet, so don't expect too much in the way of bass. It's plenty loud though-- I can't fathom why reviewers complain about volume.
+ Dual NFC receivers, one on the front, one on the back. While NFC is just emerging as a technology, if you have another Android device with NFC, you can easily throw links and such between devices (although Chrome sync handles that quite nicely as well), or buy some NFC stickers and play around with an app like NFC Task Launcher for some automation fun.

CONS
- No microSD slot. Personally, I don't find this an issue whatsoever, but if you're a big fan of local content then I can see how this might bite you. Google has long refused to put microSD on its Nexus devices, citing a number of technical and usability challenges (both sides of which I happen to agree with, but I won't go into detail here). If you're really out of space for the road, see my above section on USB OTG cables and use a cheap flash drive to expand your storage. It looks a little silly, yes, but for movie watching on the go, it'll do quite nicely. Google's on-demand download for its streaming services (Play Music, Play Movies, etc.) has so far let me keep what I want on my device.
- New layout. Again, not a huge issue for me, but if you've used Android tablets before, you will have to relearn a few things. Navigation softkeys have been moved to the center, and notifications moved to a notification bar at the top. This change has grown on me with time, since it preserves muscle memory between my phone and tablet, but some of Google's justifications just don't sell me. For one, center navigation softkeys leave a huge amount of wasted space floating around the bottom of the screen, and I liked having those keys and notifications in the bottom corners so I could hit them with my thumbs. Good thing that screen is so magnificent, aye?
- Aspect ratio. Android tablets are notorious for being landscape-only beasts, and although this device is quite tolerable in portrait, everything about it screams to be used in landscape. While this is usually fine, when reading scrolling content (such as books, web pages, and so on), sometimes Apple's 4:3 ratio is far more pleasant on the eyes, especially as such content is usually vertical, not horizontal.
- Cameras. Pass please. Tablets do not make good shooters, and while this one has an LED flash, it's thoroughly unremarkable.
- Somewhat understated buttons makes for some frustration. Power, volume up, volume down-- three buttons with distinguishable functions. So Google/Samsung, why put them all right next to each other with such low profiles? Sometimes I sleep the device instead of turning down the volume, which is just silly.
- Battery life. Please read this one with care-- the Nexus 10 does have a great battery and it lasts quite a long time. Rigorous tests have shown it lasts just as long as its competitors (the iPad included) in usage scenarios. But I have always (subjectively) found my iPad lasts longer in standby than any of my other Android tablets. Take what you will from that, but again, ultimately it does its job quite well.
- App ecosystem for tablets is a bit underwhelming. Again, please read this one carefully-- this is often leveled as a make-or-break charge on Android tablets. While I agree that the market is a little underwhelming, let's be real-- we don't ever have hundreds of apps on our tablets, and Google Play now has more than enough to cover most of my needs. In addition, the Nexus 7's enormously successful launch saw a huge wave of new, 7"-optimized apps. I expect to see increased interest in the 10.1" form factor with the Nexus 10. I've found the apps to do everything I want to do, and with some digging, I believe anyone could.
- Consumption, not production. While you certainly can use this device for production (particularly with a Bluetooth or USB keyboard), and Android gives you real filesystem access, you can't really escape that the Nexus 10 is a content consumption device. So are the iPads. In fact, the only two tablets I've seen and used that took productivity seriously were the Transformer Pad series and the Microsoft Surface RT. The Transformers destroy most Android tablets when it comes to productivity, and (I believe) are in turn destroyed by the Surface when it comes to serious Office-work and overall versatility. Obviously this is a point for debate and contention, but this is my stance based on my experiences with these devices. Feel free to comment if you disagree!

On the whole, do I recommend the Nexus 10? Wholeheartedly. Absolutely. With one little problem. The price. The Nexus 10 is excellently priced at $399 on Google Play for the 16GB Wi-Fi variant. So why is it being sold at $549 and above here on Amazon? It's quite simple-- third-party sellers routinely exaggerate the list price so that they can comply with Amazon's "list price or lower" rule, while still turning a profit on flipping an in-demand device. You can argue it's supply and demand-- I think it's dishonest marketing. Buy from Google Play if you can, or see if you can wait just a bit for the vultures to be brought down by more legitimate resellers.

Either way, I hope this helps, and just comment if you have questions!
