I first joined the forums here a few years ago when I was looking to make "the switch." Since then I have been a very happy 12" PowerBook G4 owner. I'm thinking with the recent SR MBPs, it's time to upgrade. I really do like the 12" form factor, it's light and portable. But since joining the Mac team, I've been doing more and more video work (plug alert: sketch comedy at http://goodcommitment.tv) I edit on my PowerBook a good bit and it gets the job done but mostly I edit on a PowerMac G5 with a 1600x1200 display at my place of work (after hours, of course). So here's my question. Have any of you jumped from a 12" to a 17"? How bad was the adjustment curve of the added bulk? Did you love it right away, over time or wish that you had gone with a 15" instead? Going to 15" makes sense for several reasons but that new high res 17" display caught my attention in a big way. Initially I figured I could upgrade to a 15" and eventually get a 23" or 24" external display for "desktop" work but this would eliminate the need to buy a display. Any thoughts or experiences are appreciated.
