I have enjoyed and utilized my edge almost more than any other device I've ever purchased. It served me well for reading and notes at school; a lot of my teachers even accepted my classwork and homework directly emailed from the edge. My recently purchased PE is great for reading, and when it gets dark outside I switch the book to the LCD side. Everyone is intrigued by it, but, the younger generation is more interested in the sleek "sexy" tablets. I think that's more what happened than anything; it is after all the younger generation that seems to have the most purchasing power as Generation X spends between $71 and $110 dollars a day. I think Baby Boomers, and older, tend to look at a devices utility as well as the WOW factor when considering a purchase. Although I am disappointed that it seems Beta is all we get, I don't regret my purchases.
In any case, I hope my devices last until I finish school or find something worthy to replace them. See everyone on the other forums.
