i have a friend whose school uses Macs and always has been. it's running the new iMacs with OS X, assuming it's Jag. he's also been a long time PC user alongside his use of Mac. despite hearing the great things about Mac. he told me that his experiences with it is not all that. why is this? is it true? are there any mac users who is not 'that' satisfied with their macs? any mac users who actually switched to a pc?? any comments are appreciated. thx.
