Vista is good!
I have been using Vista for over a year now, and it has been a pleasant experience. I saw an article in the newspaper (yes, I read a daily newspaper on real newsprint) that said that Vista was less stable than XP. It is simply not true. I was just reminded of this a few minutes ago. I was trying to forward an email using Outlook. There was a problem viewing the email, so I should have been suspicious of it. When I tried to forward it, Outlook hung. When I tried to close the forwarding window, I got a popup window that Outlook had stopped working and asking what I wanted to do. I chose restart. It did. Try that with XP. I would have had to reboot the OS to recover.
I have found that a good many programs will crash and will not take Vista with them. I call that more stable, not less stable.
I wish Outlook were as stable as Vista. It has been unstable since a recent update, I believe, although I didn't track exactly which one. I will try the latest SP soon and see if that improves things, probably after I do an image backup of my disk, just in case. (See my article on backups for more on that subject.)
