For me, it must have been 20 years ago in 2005. I got Kingston’s 512MB flash drive for a Christmas present and oh my how great it felt to hold so much of memory in my pocket. After that it was clear to me that there is no use for floppies to me anymore.
Has to be at least 15 years. Probably 20 or more.
I still have a few floppies somewhere around here, but haven’t had a drive that can read them since I donated an ancient laptop to a friend of a relative.
I don’t feel like splashing out £12 for a USB floppy drive right now.
Other people mention 5¼" floppies for old 8-bit computers, and I suppose I do have my old computer and drive packed away somewhere, but I haven’t touched any of that in over 20 too. I’d be surprised if any of that still works and I’m kind of afraid to find out for sure.
