I've got a Dual 2 GHz powerPC G5 which I bought in 2004 with a 23 inch ADC monitor. My wife has a 2.1 GHz 13 inch laptop bought last winter which seems to run faster. I'm starting to get a bit annoyed because some applications are starting to be intel only and my once bugatti of a computer is now decidedly toyota prius. Which of the current laptop line up should I get for photoshop and writing, surfing usage. (I can get my adc 23 inch monitor to work with laptop using the right connector which I have) Which has the most longevity I suppose? Price isn't the main issue I heard the 17 inch is a bit cumbersome? Any thoughts?
