Re: Great idea... but too expensive to "change the world"!
Wow, no kidding. Over $1000? Not a chance for me at least. In comparison, 9.7" Kindle DX: http://www.amazon.com/Kindle-DX-Wireless-Reader-3G-Global/dp/B002GYWHSQ, $199.
That's going to be a pretty hard sell, although the writing part is very cool. I think somebody produced one at one point perhaps, but I've said for a while that eInk (and similar) versus the regular LCD type screens are just too different, and devices picking either one over the other are making a compromise. Of course then, the ideal device perhaps is one with both screens available so you can read on the eInk, and play on the LCD. For that, I might pay $1000. Maybe.
So would I be interested in this if it were half the price? Maybe. It's still a tough sell. The handwriting has to be amazingly better than any other electronic writing surface I've used before. Sadly that won't be hard, but if it's as awful as writing on a glass screen, count me out.
