MiniDV still alive for some reason

I looked at some digicamcorders recently, and found a lot of them still on the miniDV standard that was popular when I first looked into these cams in 1999.

I don't get it. Magnetic disk drives have reached impressive capacities in tiny footprints, flash memory costs nothing and is fast, even smaller, and very high capacity. Why bother putting a tape in the camcorder anymore ?

I'm still using this old Sony MiniDV DCR-PC101 cam, and my number 1 problem is that it won't record because of some issue with all the moving parts on the tape writing mechanism. I fix it by literally banging it on hard surfaces until it works again, (which is the most accepted method of repair on the internet). I can't imagine buying another video camera that relies on tape at this point.
