I finally got an orbit reader last week. It's great as a reading device. 20 cells isn't as cramped as I originally thought.
The jury's still out on whether it will make a good terminal. I think the slow loud refresh and lack of routing keys kind of work against it there. I got it mostly for reading books to pick up speed, so I could eventually get a more full featured display from rehab services.
I just need a case for it. I looked on the Executive Products web page, and it looks like the case they offer is for a different unit altogether, or at least a prototype.
