Re: The old ones don't get obsolete
All my machines have optical drives still (because they're oldish), but I don't trust it for storage and I haven't bought a pre-written one for years. On the odd occasion I do try to read something (play a DVD, for instance) I find the desktop drive non-functional - presumably because of accumulated dust.
So I don't care about availability of new machines with drives. If I must have one, it'll be external so I can keep it in dust-free in a drawer.
