Well, I've decided that b/c I'll be getting a Mac desktop, it makes sense to just get a 12inch iBook for the portable. However, I have a question. Is it possible to buy an upgrade for the speed of the 12inch iBook? I know that PowerLogix sells upgrades for other Macs, but I can't find anything for ibooks. I think that Apple should have had at least a 933 Mhz option for the 12inch, and would like to know if any online store sells a speed upgrade. Thanks.
