Sharing a comprehensive verdict of this thing, I would simply say, it's like operating a spaceship.
I tried booting it up couple of times but the setup screen appeared again and again. Setting this up was a disaster.
But after it's setup was completed, the device ran like a beast. The biggest flaw in this is also the lack of titles that could be played. And also the price of the games sometimes touch the point where we can even buy a new phone instead.
After a few updates, the performance got choppy and slow. And doing stuff like playing a new game got frustrating.
My verdict would be skipping this version and wait for the next generation.
