I still use optical media, but much less so than before.
For audio and video media, CD and DVD are my first choice, but as a means to an end. I have several used disc sources, and a couple of local stores still selling new material. It becomes an automatic backup once I rip the discs to the file format needed, but the media itself is infrequently used once on my file server.
DVD+/-R and BD-Rs became secondary backup sources. USB hard drives are much more convenient, but I'll additionally burn valuable data to blu-ray, periodically testing the discs for readability.
With a Gigabit+wireless AC network at home, I have little need for optical media for everyday use. An external USB optical drive for my laptop is more than sufficient for the odd need. I'll litter available desktop PC slots with optical drives.
