I have recently bought a G4 12" iBook and am looking into buying some RAM for it. A local PC hardware Store (usually knows for good prices and decent quality) has the following. CORSAIR 266MHZ DDR ECC 512MB PC2100 $180CDN Has anyone heard of the company Corsair? And is the above RAM compatible with the iBook? I've done a search for Corsair on this forum, and it has been mentioned, but not whether it's good RAM or not. Thanks!
