My first Mac was a 12" iBook 600Mhz G3. I upgraded to a 13" MacBook in 2006, 2.33 15" MBP in 2007 and I'm selling my 2.93Ghz MBP 15" for a new MBP next week. 15" has always been a great size for me and I plug it into a 24" Dell LCD at work. 4/7 days a week I'm at home or at a cafe getting work done so I thought a 17" would be perfect because of extra screen real estate. I fly on a plane once a month and 15" is too big so I think I'll just get a netbook for the occasional out of town business trips. IDK 17" is tempting with the latest price drop but 15" I'm comfortable with. What do you think?
