Could these kick-start mobile learning?

I've been wondering recently whether the Asus eee (see here) could be a great device for mobile learning.

It's very small, surprisingly cheap (considerably less than the PDAs we were issued with for the latest project) and has apparently been almost impossible to get hold of since it was launched! They have caused quite a stir, and have been top of many geeky-types' 'must-have' list since they were announced.

While PDAs are ultra-portable, the tiny screen size and lack of keyboard could be a real headache for some mobile learning applications. Could this be the answer? Could Gareth Rees be buying one each for us for Christmas as we speak? (only joking, Gareth...)
