For once I can agree with Micheal Arrington.

I’m tired of waiting - I want a dead simple and dirt cheap touch screen web tablet to surf the web. Nothing fancy like the Dell latitude XT, which costs $2,500. Just a Macbook Air-thin touch screen machine that runs Firefox and possibly Skype on top of a Linux kernel. It doesn’t exist today, and as far as we can tell no one is creating one. So let’s design it, build a few and then open source the specs so anyone can create them.

The idea is simple and it takes the right direction: simple, easy, cheap and open source. I'm all for that. If they can build it, I will buy it. If they need it, I can help ^_^
