I also still have a few episodes and movies on VHS! My copy of Generations on VHS is worn out. I watched it constantly as a kid. I guess that means I have three copies each, of Generations and First Contact (VHS, DVD, Blu ray)! I remember it took ages for tapes to come out on 'sell through' release back then. FC came out on home video well over a year after it had been in theatres, in the UK where I was living at the time.
I also have a few episodes I taped off TV on VHS too. All collecting dust at the back of the closet now! Thank god for optical media!
