I got one of the new 2012 27" iMacs without optical disc drive. I need an ODD for various reasons (****** internet connection e.g.). After seeing that for the price of one Apple SuperDrive I can buy two (perhaps even three) non-Apple ODDs I settled on the Samsung Ultrabook-DVD Brenner SE-218BB/RSBS (Slim, USB 2.0) (4,5 stars average, minimalistic design, single USB cable needed). I had liked a slot loading drive, but a decent one doesn't seem available. Can I boot from a CD or DVD with this (or any other) ODD? Any experiences?
