My 3 year old ibook is on its last legs, but I want to wait as long as possible to buy a new one so that I have the newest version for when I start grad school in the Fall. From my previous experience going into college in 2005, I bought my computer in July, and they came out with a new upgrade right afterwards. I have heard that the macbook series is updated twice a year, once around october, once around March? Will this be true for this upcoming year? If so, I will buy right after the next upgrade. Any rumors on when this will be or what changes will be made? Is this a good idea? (Also, I was looking at the new macbooks, and why don't they have any firewire outlets? that is what half of my external hardware uses.) Thanks so much!
