I have recently purchased a 12" iBook from CompUSA. However, moving from a 1.5 Ghz IBM, I don't think its just a perception. I was wondring if its the 1.2 Ghz processor or just the standard 256 ram. I am new to Macs, so I don't know if their ram or processor intensive. My usualy run of the mill prgrams which are all used simultenausly are EarthDesk,Mail,Dashboard,Pages,Firefox,iChat,iTunes,iPhoto. Those are all opened and my cimputer still takes 2-3 sec. to open a window. Or a 7-8 sec. to zoom in on a PDF in preview. So, will going out and buying a 512 MB stick fix my problem? Or should I return it and get a Powerbook, since I got it from CompUSA?
