So? For now they're still small compared to pcgaming market and for many years to come they will remain small compared to whole pc market.
What's more, majority of those tablets sales will be either iPads or Kindles. So while I understand push for tablets in W8 making it bring zero improvements for pcgamers ,only possible grievances seem pretty weird move, considering that Windows 8 tablet userbase is unlikely to ever come close to Windows gamers userbase.
You're in for a world of hurt. Tablets and tablet based OS/apps are the future and the way MS is headed completely. If it were up to them they would get rid of the desktop entirely, but they have legacy and enterprise applications to support for the next installment of their OS. Once WinRT really takes off, the idea of a "Desktop" will be about as ancient as our great grandfathers sitting around the radio at night.
PC gaming and PC gaming devs will have to learn to adapt to these changes or be left in the dust. The days of sitting in front of your home "computer" and doing everything are days of the past and all that nostalgia you are grasping hold of so much will soon be gone. Guys like you, core pc gamers are a point percentage, fraction of the market and you are not the focus of evolving OS's and you will be left in the dust.
Change... frightening ain't it old man?
I'm participating in the Microsoft TAP program at my work, we are basically alpha testing and helping development of core/key Windows applications and design. Everything is going WinRT, and x86, desktop styled applications are a thing of the past. Expect to see them in Windows 8, do not expect to see them in Windows 9.
