I'm on the fence between a refurb non-SR MBP 2.16 (1499) or a refurb SR MBP 2.2 (1699) but would like to hear from any users who have experience with both machines that can testify on the difference in performance. I'll mainly be doing image and video editing with the MBP. Another issue between the two models include the non-LCD screen v. LCD screen, which I hear have had a "yellowing" problem. Discoloring or power savings aside, is there a big difference visually between the two? This "Crack"Book Pro dilemma has me , so thanks in advance to you Apple (err, Mac?) guru's!
