Eugh, Ned.
Vista is great!
When I come home from work, using Windows XP becomes such a pain in the arse because of the functionality that's in Vista that XP is missing. I remember how working on Windows 2000 was a pain because of the functionality that XP had over it. And I also remember how 98 was a pain to work with because of the functionality that 2000 had over that.
If I went back to Windows 98 now, I'd probably cry.
Vista has enabled me to be more productive at work, and that's a fact.
