As I've said several times before, 10 years from now, people will laugh at what slow, expensive, clunky, primitive dinosaurs today's best ebook readers are, the same way we see the laptop computers of 10 years ago and the desktop computers of 20 years ago.
The ebook reader of 10 years from now will have:
A bistable color display with the battery life of current eink but the refresh speed and resolution of "retina" LCD.
At least 32 GB of internal memory (because nobody will bother to make chips much smaller, the same way you would be hard-pressed to find an 8 MB flash drive today.)
It will be half the thickness and half the weight of today's readers.
It will cost less than $100.
The only place you will find Kindle 3s 10 years from now is gathering dust on the shelves at Goodwill beside the 8-track players.
(Oh, and if advances in use of
graphene continue to advance, that reader will likely have a CPU at least as powerful as today's desktop computers, without drawing more power than the turtles used in today's ebook readers.)
