I'm ready to add a 17" MBP to my 'fleet'. What does the forum think? Pull the trigger now, or will the 17" get a OLED screen & faster 250GB HD's at the Sept. Apple event? This will be used basically as a portable desktop system, with lots of storage onboard. Reading various posts here & in other forums I'm not sure how much the hard drive speed of the current 250GB drive (4200 RPM) effects performance?
