I use the optical drive on my iMac to burn discs from iTunes to listen to them in the car. I used to use an iPod, but it got on my nerves while driving. Anyway, I don't think I would be comfortable without a disc drive, but at the same time, I like that Apple is trying to move forward with no physical media. Do discs have a niche in your life? Would you feel comfortable without a disc drive on your primary computer?
