I actually went back to a computer with a DVD drive. I admit I'm not using a mac (I switched back to PC's) but the promise is still the same. I got a computer that happened to have a DVD drive, but didn't think I'd need it. Since then I've used it a few times to install old games I had, rip some music, nothing major but I was glad to have it. Ironically, the one time I didn't use my DVD drive was for installing Windows 8.
I think as long as I have a computer with a DVD drive, I'll be fine, although I don't need it on this computer.
