First of all, there are also satisfied users !!! ;)
When switching from the 'Nexus 7 (2013)', which I already thought was great, now I am very pleased that, with 8.9 inches, larger display and the new 4: 3 aspect ratio. The resolution is a little lower than its predecessor, but still top with 287ppi. It is at 100% very bright. Has a good viewing angle stability, and also the minimal warmer calibrated white balance I find very pleasant. In short, a great display! Thanks to the Nvidia Tegra CPU K1 tablet has plenty of power and everything runs fine liquid. So does Android 5.0 'Lollipop' just plain fun. Interested gamers should be times Dead Trigger 2 View on a Nexus 9. Is it really normal when reflected so on in a game, in puddles of water, the sky, including over flying birds? :) So, I am now not so the connoisseur, but the details I find just brilliant. Well, is probably at the 100% support of the Nvidia chipset. Incidentally, the processing is in my device in order. And, the design fits perfectly to my Nexus 5) This one has chosen a metal frame, I like very much, and the 425 grams convey any significance. Although, for a nearly 9-inch tablet, still rather light. The back soft-touch surface is very handy and makes it easier to hold with one hand. The stereo speakers on the front are expected to be great. HTC Boom Sound halt. :) Also perfectly adequate, with 1,6MP the front and 8MP rear camera. Class for video telephony suitable. Overall, I find the photo and video quality for a tablet really OK. My subjective impression is also that the battery hold out very long. Tests on the Internet seem to confirm this because even. A full charge of the 6,700 mAh battery, but can last 4.5 or 5 hours.
And yes, there are things that could be better. I also had to get used to a bit too deep-seated quietly spoken and rocker myself first. But the tap of the finger or thumb nail it has good pressure points and works perfectly. Only with the fingertips I have to push a little harder. The surfaces of the knobs are parallel to the metal frame, slightly inclined. It should be noted when operating. Personally, I'm one way or another deal with the buttons. The one now eg with 'Double-Tap to Wake' and by software also manages almost without was still mentioned. If the CPU is heavily used longer time it can be a bit warm on the back before. I love it but bearable. Possibly brings a future software update some improvement ...?
The rear front can be, in fact, even in my tablet, push maximum 1mm in the field of the Nexus-lettering. But the maginale Delle little further center, below the camera would have never occurred to me without all the reports on the Internet. Bothers me both not at all! Just as minimal display Bleeding in 2 places in the border area. Frankly, I take it, if at all was only at boot time. During normal operation, even with black backgrounds or borders, as look at movies which so often with 16: 9 therefore come, I do not see 'Bleeding' or 'clouding'.
Ok, now it may be natural that I, particularly with regard to the last point, just lucky had with my purchase.
I can only tell who is open to the Android system, should give the Nexus 9 a chance. Always the latest updates direct from Google, as usual in the Nexus series, and really pure android pleasure without bells and whistles. For those who may have had bad luck with the quality, as determined what it will do at the next batch ...
Although there are slight criticisms, I am very, very happy and forgiving at 'nem half star deduction, still 5 stars. :)))
One tip:
Of the 16GB remain from the beginning only about 8.5 left. I knew before, and close if necessary, a USB OTG cable, which you can get here at Amazon for a few euros, a fast 32GB USB stick. With the Nexus Media Importer from the Play Store folds, even without root privileges, wonderful. In my work, reading and writing, and of FAT32. :)
