The browser incorporated in the image is Midori which you can see briefly in this video at about the 7.30 minute mark:

There should be others available from the Ubuntu 10.04 repository although it went EOL (end of life) sometime ago so I'm not sure how accessible it is. Given the hardware, you are likely to need a light browser like Midori.

Hi Roger, I haven't seen any advance on those fronts. Of course, reading PDFs shouldn't be a problem. As others have done, I'll update this thread as I discover things.
