>you can only read one type of optical disc, the regular 120mm kind
Pfft. I've had to use irregular sized CDs a total of twice in more than 10 years. One was some preview disc that came with an X-Men movie and the other was a free promo one given at a concert in Central Park. Both were pretty much worthless, but easy enough to view by popping in my much less convenient, tray loading burner. Since mini CDs cost as much or more than mass produced regular CDs no one with any sense uses them.
>Slots can pretty much eat your CD
Eating a CD is again rare. It happens once in the lifetime of the drive. At that point you unscrew the cowling of the drive, get your CD out, and declare it dead. New drives are dirt cheap anyway. I've had mine for years and it has never eaten a disc, so this this isn't exactly a plague on us owners. In comparison putting up with a stupid tray is something you do constantly throughout the life of the drive.
>loudest mofo I've ever used
Increased noise level is unnoticeable to those without psychological problems. I know some wackos that won't use power supplies with anything other than punched hole ventilation (much worse than grills for air flow) because of the increased noise, so I suppose people like that are out there. You shouldn't assume normal people consider something as quiet as an optical drive to have any meaningful sound output, however.
