My new Powerbook is on the way and memory upgrade will be one of my first move. So i've been checking out forums (even dpreview.com) and Crucial.com seems to have the best reputation. Sure they have a great reputation, but, why? Compared to other sites who also give LIFETIME warranty on their memory and are MUCH cheaper: TransIntl: 1Gb = $259.00 http://www.transintl.com/store/category.cfm?Category=2503&RequestTimeOut=500 Datamem: 1Gb = $229.00 http://www.datamem.com/parts_that_fit_list.asp?M=PowerBook+G4+1.5GHz+(M9422LL/A)+15"&MF=Apple&C= Crucial: 1Gb = $479.00 (!!!) http://www.crucial.com/store/listpa...werBook+G4+1.5GHz+(15-inch+Display)&submit=Go So why do ppl tend to prefer crucial?? If a company is willing to guarantee it for life then thats (IMO) 90% of the sell.
