HP has been the biggest PC manufacturer for a few years they still want to get rip of the PC division.
Being the biggest seller in the console business doesn't mean anything.
Oh yeah HP tried to sell it to Samsung too.
Big difference is that video games/console sales grew generation over generation while the PC market is in decline.
Why exit a growing market? If anything, they make the division focus on Live and digital sales, pushing for an all-digital console to further subsidize hardware costs and push mobile/tablet gaming. Additionally, get a move on the digital trading and renting to increase digital revenue. With SteamOS coming there's more reason than ever to get aggressive on that front. I'm still in belief that in 7-10 years Xbox 4 will just be Kinect 3.0, able to stream anything entertainment related.
