This is the Cons section of the review by CNET:
The $399 price is a lot for a small tablet, no matter its features. It’s not as thin or as light as the iPad Mini, and some people won’t appreciate the highly saturated look of the OS. Also, its face buttons sometimes get in the way and there are occasional performance hangs.
Remember when everyone thought that Apple was crazy with the iPad Mini pricing? Not only is it made out of cheap plastic, it’s thicker, more expensive, and despite having a supposedly faster chip and more RAM, it lags and hangs when using it. And people still ask me why I prefer to use Apple stuff.
