The Xbox Ally X20, and the glasses you’ll have to buy with it. | Image: Asus If you asked me what I'd change about the Xbox Ally X handheld - aside from fixing Windows, I mean - I'd tell you two key things. First, give me a bigger, better screen. Even a little bit bigger, so games feel less claustrophobic and with less ugly bezel. Second, get rid of the "Library" button. I am so tired of an accidental press booting me out of my game and into the Xbox library without a simple way to get back.
