I have some hesitation whether I should buy a Nexus 9. With the Nexus 5, I am very satisfied, but the reviews here at the bottom make skeptical. Daring - won: I have the device from the MarketPlace Amazon Warehouse Deals, and could not tell the difference from the new. The display is top - no Clouding observed. At most, a very slight difference in the dark directly to the LEDs. But the iPad has the Air too! LTE, WLAN, speed - everything was great.
For size: The display is nominally less than the iPad (9.7 inches to 9) - I find it but hardly noticeable. For this, the tablet is very compact. Would opt again for the purchase.
