For the past several months, I have been using an ibook 12in, but after looking at it for 5 min, my eyes really start to bother me. What can i do? if I change it from 1024 to 800 it feels much better, should I leave it at this? Or, my brother needs a laptop, should I give him this one and get a 14in? 15 in powerbook? I need advice thanks
