When the idea of paperless books got serious, it seemed a good direction to go in. They were a bit utilitarian and not really good looking but functional. But now, all the bells and whistles have arrived with Wi-Fi, Bluetooth, web browsing, music and other features being added in.
Personally, I just want a large, clear screen with color capability to see properly rendered images. But all things being equal, the ability to throw 100+ books in a bag or pocket and go is irresistable. Like all gadgets, I will research them carefully weighing cost vs. necessary features. Stop back soon for feedback on specific models.
