I have been saving up my pennies for the iBook deal from Amazon where I would get the iBook 1.2 ghz combo 12" for 899 with rebate, no shipping, no tax. I finally have enough money, and then I read on page 2 rumors that MWSF may bring new powerbooks. I start thinking about the future of my notebook and how long it will last me. i remembered something about how tiger requires 64 mb of vram for all the special core image effects? can someone confirm that? and so i am thinking maybe i should keep saving and buy a new 12" pb instead....maybe amazon will even expand once again this rebate deal to the new powerbooks... an ibook would be enough for my needs, but i can wait, and i can keep saving....how big of a deal will this core image be?
