Hey as you may know I've not yet got a Mac, ;-( ,,yet, but in the mean time am trawling the web for info from podcasts etc etc etc, and just thought any new switchers might like this little trick.
Why not sign up for a free 60 day trial of .mac, no credit cards involved at this point.
Then when you have your account you have 60 days to check out the tutorials.
From the .mac homepage click on the 'Learning Centre' link, then make your choices from there, I know you seasoned mac users may know this already and some of the tutorials won't help you guys, but on the 'Mastering Mac Software' option there's a load of movie tutorials for us newbies!
Hope this helps....

There are a load on Apples site also, crikey there's tons of stuff out there!
