said by JohnInSJ:Plummet was a bit extreme.
Been using it since it became available on MSDN on several machines. It takes about 10 minutes of actual use to get used to the differences. Doubtful any plummeting will happen. People will do what they always do - get the new OS when they get new hardware (and some pretty nifty hardware will be coming out for this OS) while corps will do their normal three year cycle, so they'll skip win8 and continue their slow grind to win7 (HP will be getting there THIS year, according to the handful of folks I know that still work there. Wow) and a smaller group of people will upgrade. Maybe more with the low upgrade price, but more is still not many.
