What about a studio computer? One with no internet access that you need to load audio applications onto...like boxed versions of Ableton Live, Reason, Cubase, and large sound libraries...and on top of that, you need to import audio from CD constantly on an audio studio computer. Having a disc drive is ESSENTIAL and you cannot do without it. Some people just don't seem to understand this -- many Macs are used in applications in which they are NOT connected to the internet. They are studio machines for WORK -- and you NEED that OPTICAL DRIVE! YES!
Yup. And there are loads of options for that. If you're working in a studio you've already got loads of hardware peripherals connected to get your job done. No studio is every completely contained "in the box".
