New G2 HP Prime

[debrouxl]

This topic contains the largest amount of hardware characteristics and benchmarks I'm aware of.

The TI-Planet topic relays this information and adds:
* other pictures of the G2 calculator;
* notes about the Prime G2 firmware upgrade process: unlike older Prime models, the G2 rejects small modifications to the standard OS. HP added signatures and a validation upon install: if the signature doesn't match the content, the OS upgrade is rejected. Although this doesn't mean that the Prime G2 is as much of a closed platform than the TI-Nspire series (further examination is required), that's probably bad news for third-party programming on the Prime G2...
* I've started documenting the contents of the Prime G2 OS image. I stopped when I found what looks very much like the signature data. Going further in an efficient manner requires making a tool similar to imgmanip for the TI-Nspire series, and I didn't have time to do that yesterday evening.
