Should Microsoft come up with their own portable gaming device similar to the PSP(NGP) or the 3DS?

It would be called BINRAGSAIS (because its not a real gaming system and it sucks). But actually, no, because Microsoft has to get their hands on every aspect of technology and it annoys me. What next, they're gonna start making candy? They really need to stick to making computers, because now they are so freaking busy trying to expand their products that the computers are outdated by about 50 years compared to the other computer companies. They already own the computer world anyway, why try to dominate everything else? Also, if they EVER try to publish books I will bomb every headquarters they have. >.<
