The combo drive on my macbook is severely crunched and won't even let a CD slide in without a lot of force, so I need to replace. I am seeing a few reports on the interwebs that the Macbook, as opposed to Macbook Pro only has room for a thinner-than-normal 9.5mm-tall optical drive, not the normal 12.5mm-tall ones. Is it true? Has anyone had success installing a 12.5mm-tall drive? Where in the world can I buy this 9.5mm-tall style? I'm otherwise loving my new macbook. I came as a Windows power user and programmer. OS X is just way better for development!
