Agreed! Received my Nexus 9 yesterday.
I can confirm:
No significant light bleed at all. In fact there is almost absolutely none except for a very, very, very tiny amount on one corner, however even in total darkness when there are black bands on the screen this is not noticeable and I only discovered it by tilting the screen at certain angles in the darkness and seeing some slight change in light bleed at that particular point on a particular angle.
FWIW my iPad screen (the high-res 'New iPad' that became old after 6months) is terrible in terms of colour consistency. I had the first one replaced but the replacement unit is no better - really noticeable yellow tint that fads from one entire side of the screen to the middle of the display, at which point a pink tint fades on the other half of the screen! Does my head in.
Very slight springyness on the middle-back of the cover. I wouldn't have noticed this except I read about it on a review and tried pressing the centre-back panel of my own. Moves ever so slightly but certainly not enough to feel or notice during normal holding or use.
Buttons are a tight fit. But as noted elsewhere, they sit too flush with the device and would benefit from being slightly more raised. First world problems...
It does run hot when under load. The heat generated appears to come mostly from the top left (or right?) of the device when downloading/loading a lot of stuff or running graphics-heavy games. No noticeable heat under other circumstances (web browsing etc.)
It's fast like greasy unicorns riding lightening bolts in the middle of a snow storm raining down drops of grease at the speed of light. Seriously I don't understand how any reviewer of this tablet managed to get it to stutter even once, doing any number of activities simultaneously. Example: no slow down at all whilst transferring a 1GB file over WiFi between my phone and the N9, whilst torrenting another 1GB file, listening to Google Play, installing a large game (Hitman Go) and surfing the web. How much more can a person do simultaneously?!
It's pretty small. And is generally better for it. Compared to my iPad is much smaller and lighter (I have a pre-Air iPad). The screen is small enough that swipe-based typing is manageable and efficient, and the device itself is pretty damn light. I found myself using my Nexus 5 less to read regular news/web browsing because it was easier with the N9 and - glory of glories - the N9 gives you an option to set it up by 'restoring' your Nexus 5 profile (allowing you to choose which apps you want) including all the user accounts, settings etc., so I was right at home with the N9 straight away!
The camera is fine/ok. I doubt anyone will use this to replace their phone camera or dSLR and why would you? It's hard to use a tablet as a camera! That said, it's fine for what it does and the colour balance seems accurate under a variety of lighting conditions. It does acceptably well in low light but it won't blow your mind.
The sound is pretty amazing. The front facing speakers make all the difference compared to the bottom-firing iPad speakers. It makes the iPad sound like listening to a gramophone.
Lollipop is an absolute delight. Blows iOS8 out of the water but a country mile. Lollipop is consistent in every area of the system in terms of animation and behaviour and it's awesome. I have both iOS8 and the N9 and side by side the N9 makes IOS8 look a full generation behind.
I've seen several reviews that gave the N9 fairly average scores but I can only assume they received pre-production units. I've experienced absolutely none of the issues it's been marked down for (noted above). Buy this tablet - it's amazing.
Hope that helps anyone contemplating buying this device. The only reason you have not to buy this device is if you prefer manufacturer skins or simply don't have the coin for it.
