I have been using htc nexus 9( 9 inch) tablet for alost a year now. I am not going to give you the specs of the tablet but rather talk about its performance
pros-1) its a nexus device so all the updates comes pretty early than all the other android devices.
2) screen size a quality is more than enough for a rablet( watching videos is a good experience on this tab) .
3) it comes for both wifi and wifi cellular choices.
4) value for money considering the specs of the tab and stock android.
cons-1) this device has got some series heating issuies. some times even the headphone jack heats up while using the headphones.
2) over time my tab has become slower and slower and now it hangs a lot.
-i liked this device as a whole from the time I started using it but now, almost after a year of use I get frustated even while browsing as it hangs a lot
