finally! I finally decided to buy a MBP. I'm gonna sell this PoS PC Dell E1505 that I currently use.. tired of the overheating.. the AIM suddenly not showing my buddy list .. the stupid wireless internet interface.. The only problem now is that I want to wait for the new line of MBP's to come out. then i'll have to make a decision on either getting a 15 inch or a 12 inch. Any ideas on when the new line will come out? How much will it cost to upgrade from Tiger -> Leopard? and.. say if they come out on Feb 20 during the announcement whats the fastest way to actually get my hands on one of the first macbook pro's before they totally run out either online or in store? I'm a student so i can get out to the apple store on a tuesday morning
