good choice with the 3 year warranty ed, i wish i got it for mine ~_~
also one thing that bothered me when i started using OS X is that i thought there were no hotkeys and it was all clicking. toooooo much clicking. after using it a little, i learned the hotkeys and they're really a great help. you probably know the "alt tab" with apple + tab, but the best and most useful one is -- cycle through windows of the same program with apple + `. maybe you already knew this, but if anyone doesn't try it!
i also have a side question? does mac still sell those little weird remotes with their computers? they could control itunes, or frontrow whatever that interface is called. good design flaw is that it works on EVERYONE'S COMPUTERS. i used to bring my remote to class, point it at peoples' computers and press play

god, its hilarious.
