I have been toying with the idea of buying a Mac for probably two years now. I have been a PC user all my life and love them, but certainly see where Macs could be a big advantage with my work going forward. However, I have never been so nervous to buy a piece of technology in my life! I feel like multiple times a year, Mac comes out with these groundbreaking hardware features that every Mac user who purchased in previous cycles are jealous of. Multi-touch track pad. Glass pad. Aluminum body. Backlit. Etc/etc. I love the new MacBook, and since my PC is on it's last legs, I would love to buy the new 2.4ghz. But what is going to come out in 3 / 6 / 9 months that is going to make me completely regret buying this? Helps!
