I'm in the market for a new laptop, saw on Digg that Macbooks got upgraded and Macbook Pros also received bigger options in RAM and hard drive. Furthermore, new Leopard OS came out and all computers are installed with it, shouldn't all Macs say Buy now, recently upgraded!? What warrants an upgrade? Also, I've been looking all over the archives for some indication of a MBPro update in January as said around the forums, can someone explain to me what it is or what it will improve? Thanks, I'm new.
