I'm "fretting" because this is the first step on a long road towards the planned obsolescence of Windows 7. Which in turn paves the way for the planned obsolescence of the traditional Windows desktop for consumer products. Which finally may spell the end for open mainstream computing as we know it.
And worst, there are people that seem to relish this idea.
nah. Obsolete XP fine, 7 will be around for ages.
Watch 8 get mediocre uptake, then when consumers start getting it force fed to them via preloaded laptops etc there will be a backlash, and Windows 8 SP1 will reduce the in your face nature of Metro so it becomes more like an option to the desktop like Media Center.
