Comment on Parallels Desktop for Mac

Parallels performs well with Windows XP on my new Apple Air. I have tried Fusion but that was confuding for me to switch my windows machine to mac and the only solution was Transporter from Parallels. Also Parallels represent a great integration between OSX and Windows, so I really enjoy it.
As for VMware I can say that their performance on Vista is a bit higher but lack of compatibility and features for me sound bad.
So, I'd stay with Parallels.
