Given the meagre specs of touch, I would recommend Jota or a similar android editor as simple and light as possible. If all works correctly I am going to buy a touch just for connecting it to a keyboard and write outside. As you, @andrewed, I have been looking for an ewriter solution for years. I still send emails to vendors (bookeen, are you reading this?

) in order to make them know that there is demand for an off-the-shelf ewriter solution
I monitorized pixel-qi, mirasol and liquavista solutions from the beginning of the public existence of these technologies, but I grew tired of promises. Indeed, a sun-readable netbook would be nice too, but... 1000$?
Anyways, thanks and congratulations for the initiative. I'm publishing it in Spanish @
