Why hasn't this happened yet? Sony's got the PSP, PSP Go, & PS Vita. Nintendo's got Gameboy, Gameboy Color, Gameboy Advance (SP), Nintendo DS (Lite,I,3DS). I'm truly surprised that Microsoft hasn't produced a handheld XBOX yet. Considering that NVidia, a well known graphics company, has produced a handheld gaming device! What is going on Microsoft? Please don't tell me you're going to let Nintendo, Sony, & NVidia beat you in handheld gaming consoles? Are you?
