Uhm,
regarding the solar-power issue.
I read the following on their spec's page for the Papyrus:
- Micro-USB 2.0 with data transfer & power supply
So the Papyrus is not only dependent on solarpower, but apparently can be recharged either from a PC or the power-outlet.
See on this page, right column, bottom line:
