Over the next few years with the rise of ultrabooks installed with W8 & decline of desktops/traditional laptops. In order to compete with ARM, Apple, Google .. MS is going to have to start taking casual gaming MUCH more seriously. The Intel integrated GFX will be the benchmark baseline for all mobile app devs to target & release games to the W8 store.

Steam probably won’t survive the decade, mainstream consumers don’t use it & game dev’s will primarily target the W8 Store. That’s probably why Valve is desperate to get into hardware as they know the integrated W8 Store is going to eventually kill Steam.

My only real concern & the reason I still use a dedicated PC hooked up to my TV, is heat. PC games will cause your UB’s fans to crank up full blast & casing to get very hot. So that really worries me that it would kill my sealed internal battery & essentially make my device worthless. While I know the idea of an all-in-one device that does everything is HIGHLY appealing, unless someone smarter than me says internal heat won’t damage the battery then I would still recommend a dedicated gaming PC or console to most people.
