I had loads of cassettes as a teenager, and made mix tapes for family trips in the car as well as for girls I liked multiple times. It was great fun and even on my first tape deck (a Sharp RT-100) it could sound reasonable - even better on a Fisher (with auto-stop!) which replaced it and then on an Aiwa AD-F410 (auto-reverse!!).
By my mid-teens CD was my main format but I was still playing lots of LPs too, on a Pioneer PL-12D and Sansui P-D15 (the Pioneer much the better of the two). At 18 I met my first wife, and I was pretty much made to drop vinyl and tape, with limitations on CD as well but I managed to cling onto that with a Denon DM-30DAB and matching SC-N50 speakers (the only thing I was allowed when we moved in together).
Post divorce I scraped the money together to buy a decent system (Arcam CD73T, A65+ and Quad 11L) but it was a while before I could add anything else. When I did, it was a Project Debut turntable (the original one) and vinyl has only ever left my system for very short periods since, in fact I've had several nice turntables (Thorens TD150MkII, Michell TecnoDec, Rega Planar 3 with TT-PSU, and my current Project). Tape, on the other hand, has hardly been seen expect for a brief time with a Technics RS-BX501. The motorised door was a novelty, I quite liked the look of it and it sounded reasonably good, but tapes were becoming harder to find (even blanks) and the sound and longevity just didn't match up with my CDs and LPs.
I got a couple of cassettes last year as part of special launch 'packs' with new albums (The Coral and Birdy), but they're still shrink-wrapped and it's unlikely they'll ever get played. I no longer own any type of cassette player, and I don't see myself buying one. I've recently wrestled with myself (yet again) over trying to simplify my system, but I've accepted that when it comes to the crunch I will never simplify further because I love my CD and vinyl collections too much, and in my present system both sound superb. Add the whole musical vista offered in very high quality by streaming, and there's just no place for an outdated, hugely compromised format like cassette. It might appeal to hipsters who want to show they're different, but it's a non-starter as far as I'm concerned.
