Agreed, you can have an on-screen keyboard but it's not really practical to use. And even if it's just for gaming, many games still require some keyboard input from time to time (like naming your character/save file). It'd be a quite disappointing to be locked on the first screen of your game because you need to input some text and can't.This thing is super weird.
Windows isn't very touch or control friendly in the OS. I guess they chose it for game compatibility but it seems odd to not have a keyboard.
It's got a usb port...Yes i understand that. Windows is not really built for use without a keyboard or mouse.
