It's been a while since my last entry, so here is a little something. As requested, here is a little Ben NanoNote vs. Zipit Z2 comparison.
The machines have both a very similar shape and size and their specifications are also not too different. While the Ben NanoNote was meant to be Open Source hardware the Zipit Z2 was built as an instant messaging device for teenagers and was then repurposed by the hacker/free software community as a more or less general purpose Linux computer.
