Vista was terrible. Windows 7 is much better. I too was reluctant to
leave XP but was forced to and now I like W7 better. I even set up an
emulated XP for the occasional programs that might refuse to work in W7
(most do just fine) but have not used it in months.
I have 98SE, XP Pro and Win7 Enterprise all working in Virtual PC. Started
doing that when DVDx wouldn't work under Vista and the new DVDx 4 is
crippled in it's output resolution unless one pays so easy workaround. 98SE
already had license etc. for and small footprint anyway so why not. MS
provided a downloable vm hard disk image for the Win7 environment although
it's "unactivated" so only good for so many days. For my usage though and
as they point out, throw away any changes and it'll last forever by
reverting back each time is all I want it for right now.
