Hey all, I'm taking the plunge and buying my first Mac in the next couple weeks. I was leaning towards a 24" iMac at first, but as I already have dual 20" Dell monitors for my PC, I decided to just get a MBP and hook it up to the dual monitors while I'm at home and get the portability. I was pricing out MBP's though and I noticed that Apple charges $250 extra for the 2.6 GHz model over the 2.5 GHz. I want to get a top of the line machine, but is the extra 0.1 GHz really worth $250? Can anyone comment on the difference in speeds of the two? Would I really notice it? Thanks!
