I've never been very excited about belt clips anyway. I would rather have a
thin plastic case that leaves the keyboard accessible and maybe a neck strap
so the thing wouldn't end up on the floor. All the clip means to me is that
I can't put the unit flat on a table for braille input.
The $65 charge for a new case doesn't suprise me and is probably quite
reasonable. They probably have to charge for the whole case even though you
only need the back half. And who knows exactly what is involved in changing
the back half, it might be quite simple or somewhat complicated, I'm not
about to take it apart to find out. If they sent you the case and you
screwed up then there would be even bigger problems.
