Infrared is just the "colour" of the light the lightsource is emitting(in this case a LED), for cmos led sensors it can be either red or infrared, regardless of the visibility for the human eye its still just a LED.

0o, both use PAW3305DK, but with different Lenses.
Kana, Kinzu v2 and maybe the Zowie FK/AM or the G100s could work for you, everything else pretty much has a high Arc in the back and stays flat on top. I know that problem too, i wanted a lighter ambidextrous mouse for faster/more...
