Internet Tablets for Education?

What do educators think about students using mobile internet devices for education? For example the Nokia 770.

Its an internet tablet with wifi built in, 800×480 touch screen, Linux based OS, bluetooth, Opera web browser, GTalk (VOIP), IM, email client, word processor, and I’ve even seen a Citrix client for it. Keyboard is not included but has been known to work via bluetooth. Retails for $359.95 USD.

I haven’t used this device but I thought it could be handy. Here are more URLs about it.
