My eight year old son has fallen for the PE too. What he is excited about is writing by hand onto the computer, and drawing. He is in a big creative phase, and I am unwilling to share the PE with him all the time, esp as they're discontinued and will continue to get harder to find. Plus the e-ink screen he's writing on is a bit small for him to accomplish much; in 40 minutes yesterday, he wrote a 16-page pdf story (with illustrations) that ends "to be continued."

He'd been using notebooks, but often got frustrated; he says he much prefers the eDGe.

Any ideas for a not-at-all-expensive touchscreen device (stylus enabled) that's fairly sturdy that he could use for writing and drawing? It would be good if it had at least two to four hours battery life, so he can take it in the car. Wifi is fine (don't need or want 3G).
