To get a mac user's perspective, check out the series of podcasts on 
www.blindcooltech .com

Mike arrigo is a mac user, and a ham.
In a series of ten or so sessions, he takes you throu the mac, showing its 
good and bad points.
He also has a specific session on running windows xp on a mac with 
window-eyes.
I was impressed.

My next machine will probably be a mac, but that will be a while. Finances 
won't allow it right now.
