I have a rev A MacBook and I'm on my second MatSHITa drive and I'd say that yeah, they're the worst drives I've ever had on a computer. Very picky about media and I've had problems reading discs that were burnt on it (many different brands, all verified OK after burning). I'm not fond of the slot loaders. Fortunately I have a 5 year old Compaq on my network that still reads discs flawlessly. Perhaps it's just a rev A thing but nearly everyone I know with a MB/MBP in this part of the world has had their superdrive replaced at least once. Then again many have had a new logic board or two as well...and power adapters...and...sigh. What happened to QA?
