I have been waiting for this upgrade for months. I can hardly wait till I get it here in Canada. Ship 5-7 and another 5 for Fed Ex. Once I get it I will be busy learning the OS and transferring all my data from the external drive I used to save all that data from windows. Any suggestions for learning all the ins and outs or should I just use trial and error to muck around and see what I see? Glad to be done with windows. Although I will use Boot Camp for some games.
