I need some advice on selecting a reliable and moderately priced iBook. I might go to 12'' to save some cash and also go with a smaller HD (30gig). I'm sure that will be substantial for running design software but i'm not sure how long the HD will last before I fill it up. Are there any other students using an iBook right now that have pros and cons on this laptop? Thanks. p.s. If you have one for sale please let me know.
