Hi Terry, the problem is that you may want the mount to serve both purposes. Granted a computer is almost (but not quite) a necessity for astroimaging and if that is your only interest, then a mount that needs a computer doesn't suffer any disadvantage. But sometimes I want to go visual, in which case a computer is a PITA. Even a hand paddle is a bit over the top if you are showing a friend a selection of bright stuff.
So because I do visual and imaging, I don't want a mount that insists on a computer for its use.
