I've been working with a macbook for the last few years. It's been good to me, after a RAM & hard drive upgrade, but the superdrive is starting to show some problems, my wireless and battery aren't what they used to be, and for the pro tools/logic work that I use this for 90% of the time, it's pretty slow. So I've been waiting for a few months for the new iMacs to come out before I would even contemplate upgrading. Now that they're out, they do everything I need them to, but I don't know if I should upgrade yet because: USB 3.0? Light Peak? Blu Ray? The thing is, though, as early as it is, I'm leaving for college in a year, and I want a computer that will last me a long time while I can still afford it. I don't need a portable, as I have a netbook and a macbook, and I could really use a desktop. Opinions? Thanks.
