I installed Vista Ultimate 32 bit on a pc on friday.
It seems ok, not that much different to XP but it has some features that will probably stop users from getting the malware and possibly viruses as easily as with XP and earlier OSs.
It was annoying me until I fopund out how to disable this feature but I would leave it enabled for anyone who isnt too sure of how to do things on pcs or has kids.
Each time you want to install or even access some programs or functions of Vista a message appears asking if you chose to do this or not.
If yes then click to continue.
This should stop the people who just click on popups and stuff like that then get lots of crap on their pcs
It does however come bundled with IE 7 which is taking me some getting used to as its quite a lot different in its layout to IE 6.
Some older programs wont run on it, I couldnt install Norton AV 2003, it needs 2006 or later.
My early version of Nero 7 Premium wouldnt install, it said there were known compatability issues with it and refused to let me install it.
The latest version of Nero 7 Premium is however Vista ready and has installed ok.
Time will tell whether its worth staying with or going back to XP pro.
There were 15 security updates downloaded yesterday even though on friday it said it was up to date, although that was after I installed office and a few related to office
