Awesome project. Kind of off-topic: I wish I could buy such a machine or something similar as fully assembled mini laptop device with a large character LCD display. I've been looking for fully programmable, full keyboard devices with extremely long battery life (weeks not days) for years, and all I can find are old pocket calculators and vintage machines from the 80s. I've had high hopes for the PocketChip, but there you go: 5 hours battery life only. :(
