I was just reading the forums, because I wanted to get some new ram for my 12" 1.5 Ghz Powerbook. Ok, so far I know its 200pin, DDR 333, and it has 256built in plus a 256 hooked up to the slot. So, here are my questions. Would the difference upgrading to DDR2 Ram be noticeable/worth the money? Crucial said that the ram limit is 1280MB? is this true? if it is ****ing ******** I am a corsair fan because I've used their Kick ass ram for my gaming rig and it just rocks, so It'd be cool to use Corsair? any issues with it? or for not -getting-an-ulcer's(sp?) sake should I stick with Kingston, Crucial? Thanks in advanced.
