Well I started off with the iphone then made the mistake of installing Vista on my PC that was less then a year old. Now I posting with my new 24" iMac!! Yea!!! I had a few questions though ... I am a long time PC user and I am a bit lost on how to do everything. I am getting the hang of everything but was wondering if there were any type of cheat sheets for us old time PC users!! Thanks and hope to get a bit more fluent on the imac!!! PS... I did the Leopard upgrade and went fine but was a bit slow!! 1.5+ hours.
