Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
ridiculous.

Everyone has a wiimote already, with a little internet searching and bluetooth connectivity you can make it work perfectly on your computer. I already use my Wii GH3 controller to play Frets on Fire and I've dabbled with the FPS mods allowing you to play any shooter with the wiimote.
...got a wiimote with glovepie and i played Virtua tennis, playing need for speed like a steering wheel...and ocassionally FPS games...so...i doubt im paying 100 bucks for this...
