I think Vista Home (or whatever it's called) is going to be a very tough sell with all the DRM stuff that MS is pushing."With Windows Vista you'll be able to download and play music from your favorite artists." (Which will only be available in the latest DRM-ed formats, since we're selling the RIAA the wet dream of true anti-copy technology.)
But maybe they'll just wipe it and roll out Win2k or XP anyway.Until the VP in charge of IT comes does some work at home on the new PC he just got, emails it to his work account, and can't open it there. Then someone tells him he's already paid for an enterprise license for the latest version and he tells IT to put it on.
Windows has always made headway by reading everything, and making its latest formats unreadable to everyone else.
