I'm interested in seeing how many of you mbp 2.4 penryn owners are satisfied, happy so far with their purchase. I have one as well, got it when they first came out, but I sometimes wonder what might have been with the 2.5's 6 mb L2 cache and 512 memory, especially now that i'm about to run it with a 30" ACD. Any regrets people?? Was the money saved worth it? How about future proof? Sorry if this thread sounds stupid but..I don't have any mac friends in real life (it's a windows, dell world) to talk to about issues such as this.
