After a year of college with a Powerbook:
If you are a Apple user, you probably plan on using your laptop, which is good. Too many people at college buy laptops, giant laptops, and then
Don't Use Them. Ask yourself if you really want a laptop, and not a desktop.
Having said that I used my powerbook like mad all last year, and sometimes it was even in my room
[see specs below]
I use my computer for a few games, and major photo editing. I'm glad I go the Powerbook, but only because back when I got it, the span between the PB and the iBooks was far larger. I'm not sure there were iBooks over 1ghz when I bought my PB.
For your use I would think the iBook will do just fine, better than fine. I would suggest getting yourself to a gig of ram as soon as you get the computer. I only just did this last week (went from 512 to 1.25) and WOW, let me tell you. I'm kicking myself for not doing it sooner.
Best of luck to you though! Strut that iBook like it's a giant gold necklace
