Besides speed what are the pros and cons of the iBook vs the PowerBook? I'm going to use it at home to surf the Internet, mail, iTunes w. iPod, maybe a little programming - though I probably will never have the time for it, a game like Sims2, writing, dreaming... - Which one gets the least scratches? - Does the weight difference matter in daily use - say lying on the bed, sitting outside etc. - What is the most annoying thing about either? - Are there differences in battery life? - If I buy a new thing there is often a thing I didn't knew about that should have been in it. What would that be here?
