Microsoft should really release a 'Gamer Edition' of windows
But how? There's no market for it, because very few people use their PCs just for games. If they were to release one, it'd be a marketing nightmare. If it was the same price as, say, Home Premium, people would probably rather get HP because it's got more features. If it cost more, people would rather get HP because it's cheaper, and if it cost less, you might find people buying "Gamer Edition" over HP to save money when they really should be getting HP.
Besides, do we really need yet another version of Windows?

I can't really imagine what benefit a gaming edition would have anyway, other than slightly reduced overheads. For a gaming PC with a good CPU and plenty of RAM, those overheads are negligible anyway.
The only people that would buy a Gamer Edition are hardcore gamers and people paying too much money for Alienware PCs. It'd also give the impression that the other versions of Windows are no good for games. MS is far better off making Windows more gamer-friendly in general, rather than splitting it up.
