PC World has published an interesting article on what the claim are the top 18 software features Windows Vista (and XP) should have but don’t.
I disagree with 3. Back to My Mac: if you were smart enough to keep automatic backups on Amazon’s S3 service then you could get the file easily and pay a lot less than $99/yr. A lot of the other features are already handled in windows by free third party software – why should Microsoft reinvent the wheel?
Overall I see nothing in their list that would make me ditch XP on my main PCs for Mac or Linux (even though I also use and like Linux).
