-The Display does not have the best viewing angle
-Sometimes It hooks briefly, such as when an app is updated
-The Brightness of the display can be "too light for darkness" "too dark for outdoor use" set and only between.
-The Case does not have the best feel. Plastic. Feels subjectively better as the "slimy" Plastic Samsung devices or iPhone 5c, but not as good as Nokia or LG.
-There Are no custom ROMs and is typical Intel probably be no. However, Acer has released only 4.4.
That said, I can not complain. Who the quality of a Nexus 7 is expected for half the price here will be disappointed. I use it daily and am satisfied.
