Is there any consumer electronics supplier which does do that? Nokia have, for the devices to date, given out 500 new devices to the people who've best made a contribution to the device and the community at $/€ 99. That's a pretty generous discount. If you want one, you make the Maemo ecosystem a better place :-)

There's been no announcement on a new device, so no. I wouldn't expect it to be wildly different and, with the more discrete power management available in OMAP3, perhaps a little better.
