Floppy disks? The technology is passe, but the idea isn't. Those no-suitable-name USB thumbdrives, and pocket-sized USB-powered hard drives, keep the concept of in-hand physical data retention & transport alive.
Wristwatches? Aside from knowing the time when there isn't a clock (or six) around, it's largely jewelry at this point. People still wear rings & necklaces, even though not for transport of precious metals for value.
VHS tapes? Just one step in the long line of audio/video media, all eventually abandoned. I keep my VCR to play kids videos bought at a library 10-for-a-buck get-rid-of-'em sale; cheap way to get Disney movies that will probably be wrecked eventually anyway.
Beepers? Proto-cell-phones.
Film cameras? One of the few technologies on the list that really is going dead, not just evolving to the next form.
Typewriters? I was at Smith Corona when they went under (long story about a short time). One technology that SHOULD have lasted longer but for shareholder demands. Neatly filling in a paper form still needs a tool as easy as a typewriter.
Walkman/discman/minidisc? Evolved accordingly. Hello, iPod.
Dial-up internet? Networking using a system not designed for networking. A hack-job until proper networks arrived (and I'd contend still not really arrived).
DVDs? Physical pre-loaded data storage is fading in favor of broadband. CDs, computer program media, etc. - bye bye. Blu-ray still holds out for that last vestige of high-bandwidth content.
