I've had several devices and I ended up with a 64GB iPad Mini Retina. The best tablet by far.
Oh, my... the stickers.
It is really expensive.
I think the problem here is not Microsoft. It is Infinity Ward. It is obvious that their game engine is getting old, and they didn't really optimize for Xbox One.
Also, COD:Ghosts and BF4...
Until they build a 4:3 tablet, they're doing it wrong.
