Hmmm, I'll have to think about that one some more. Ironically, what directly comes to mind for me are two mice: - The Genius DX-Eco - The original Roccat Pyr

Hmmm, I'll have to think about that one some more. Ironically, what directly comes to mind for me are two mice: - The Genius DX-Eco - The original Roccat Pyra As far as I can tell, both aren't actively produced anymore. The DX-Eco was an attempt to power a wireless mouse with a capacitator that is loaded to full charge (~4h of usage) in 4 minutes. The Pyra was just a great mouse (and its successors have lost a lot of its great features): Optionally wireless, running on easily exchangable AAA batteries, not too big, good sensor, not too pricy (~30$, if I remember correctly), didn't need the crappy Roccat driver to work properly. I really wished I had bought a second one when mine broke. On second thought, combining the two would sound even more exciting than bringing a single one of them back.
