I am looking to sell my emac and buy an ibook for portability issues. I have looked at the specs to see if the ibook is comperable to the emac but some of them look greek to me like video memory etc. Basically I want something that has pretty much the same specs as my emac but is portable. will the ibook do it? BTW, if I had all the $ in the world I'd buy a powerbook, but that is not an option.
