Google's Nexus 9 is a big departure from past Android tablets in several ways, not least of which that it has a 4:3 aspect ratio. It's also a 64-bit tablet with a more premium price point. There's no followup to the 2013 Nexus 7 with its low price. A lot of the early reviews were mixed, but does the N9 seem better after a few updates? I've been living with the Nexus 9 as my main tablet for the last few weeks, so let's figure it out.
Design and Build Quality
You've probably heard it said many times that the Nexus 9 bears a striking resemblance to a scaled up Nexus 5. Well, that's definitely true. The back is made of the same soft touch plastic as Google's 2013 flagship phone. The rim around the edge is made of aluminum, though. It seems like there's some variation in how that plastic back sits. Some units have a little bit off give as the plastic pops out from the frame in the middle. This isn't an issue in my unit, and I suspect it won't happen on newly manufactured tablets. Even in the worst cases, it doesn't seem like a structural issue, just annoying.
The buttons are positioned on the right side (in portrait mode) and they aren't awesome. I'm not sure why so many OEMs have trouble getting buttons right, but it happens all the time. The N9's buttons are mushy and have low travel. On some units, they are almost flush with the side of the tablet. Mine isn't that bad, all things considered. It could be better, though. It's sounding like newer tablets aren't suffering from this particular defect.
The question you have to ask is, does the Nexus 9 feel premium? The unsatisfying answer is "kind of." The device itself is solid and doesn't flex. It feels dense, but not too heavy. The buttons are definitely a sticking point and the back will be divisive. I really like soft touch surfaces, myself. I'll take a soft touch plastic device over metal any day--they're just easier to hold. It does get fingerprint-y, but that's the price you pay.
Google says the nexus 9 is 7.95mm thick, but I feel like that might be a tiny bit generous. It's still definitely under 10mm and it seems better balanced than most tablets. Overall, the Nexus 9 doesn't quite feel like a $399 tablet. That's not to say it feels lousy, or anything.
