I do. Three reasons:
1) It's cheap fun looking for what you can find without knowing what you want in charity and junk shops. I bought cheap vinyl when everyone wanted CDs, cheap cassettes when they went out of fashion. I'm now buying CDs for next to nothing.
2) At some point half of the people getting rid of CDs now will be looking to replace them when they become fashionable again. They probably won't ever be as collectible as vinyl, but there will be a demand. My daughter has recently paid through the nose for a vinyl copy of Pulp's 'Different Class'. I tried to point out to her that this was not an album that anyone bought on vinyl in the first place. Years into the future people will end up wanting the format that they first bought a record on and with the 90s-2000s that is the CD. These are antiques of the future. The new vinyl copies of old albums that are being made now will be the equivalent of Woolworth's 'Nice Price' range.
3) Spotify is all very well for listening to music, but you can't keep piles of it everywhere to irritate my wife.
I could be wrong but I can't see CDs coming back the way vinyl has. The cases are flimsy and easily cracked, they scratch easily, they don't have the enjoyable physical form that vinyl does. Maybe it's just me, but I've never gained any enjoyment from CDs as a medium, even when they were "popular".
