Anyone know why Crucial's Apple memory is so much more expensive than the non-Apple memory? I'm looking to get 1GB for my PB G4 1.5, and the Apple-compatible version (CT434204) is $218 while the non-Apple (CT12864X335) is $152. Both are DDR PC2700, 200 SO-DIMM, NON-ECC, unbuffered, 2.5CL, 128x64, 2.5V.... I can't see any difference, but one is 50% more expensive. Anyone have any ideas?
