Or is Apple going to force us to buy a USB optical drive like before? I really do hope they release the new OS on a thumb drive at nearly the same price point as the regular DVDs. Who knows, with the Mac App Store and flash storage just becoming cheaper and cheaper, optical media might be going the way of the cassette. I sure hope so. Or, are we going to be able to buy a digital .dmg copy of the OS from the Mac App Store?
