Yep. I'm using it right now.
However, startup is very affected by application. There are alot of nasty app there which start as system starts, this lengthen my boot time. After that, it's just quick.
I think, it is the only Android device with best physical design. I know it has limitation with android version and screen size, but, it's worth the style, plus I'm not so enthusiast. So, it's so stylist.
For your information, I already rooted this device. So, should still be okay if you want to play with this device.
