I've been waiting for these -- digital displays for music scores. At $1600, they are expensive, but should lead to larger e-reader displays.
Imagine, no more page turning during concerts -- just a tap gets a nice, lighted view of the next music page. And you won't need a brief case full of over-priced paper scores. Music always cost a fortune because print runs are so small.
It will be very interesting to see where this takes us!
