Heh, depends entirely on what someone is willing to pay.  Could be anything, really.  Someone wants one, somewhere, though, because at least my sister would: she reads things backwards.  It would be much easier for some people, actually.  Now, if the screen ever reversed the other way, that would be akward.  And I wonder how in the world it did it so cleanly (what did you do, TI?)... At any rate, I wish you well - it is an unfortunate occurence overall!

Try the proper reset methods:

Press and hold (in order) [2nd]+[Left]+[Right]+[ON]  (clears RAM)
Remove a AAA battery; replace it while holding [(-)] and [)]  (clears RAM and archive except OS)
Finally, maybe try redownloading the operating system

If these don't help, it must be the LCD that's toast. That's a pretty strange failure mode, though.
