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!"
Paul: I think your taking the idea to literally.
The idea isn't to install Linux and put huge neon "lying" lights all over the place. Its talking about an interesting opportunity for hackers to interface with the human body, rather than just machines. Its also a fun project to learn to understand how the machine interprets the humans stiffness, and to play around with electronics in general.
Its not about making a lie detecting chair, its about making a chair detect lies. Its about the challenge and the experience. The point is not to come out with a awesome chair, but to have learnt more about technologies interaction with people.
In your example, it would be discovering that your camera is a downgraded model from a 10MP camera, that it has the potential to be 10MP, and hacking it so that it is 10MP.
