You'd think that camera makers would run out of clever new tricks. But now Nikon has pulled a pair of point-and-shooters from its hat designed to astonish and enthrall users. The Nikon CoolPix S70 is the first handheld outside Apple's iPhone and iPod Touch to incorporate a multi-touch screen. The other rabbit is the Coolpix S1000pj, the first camera that is also a projector. When you see it in action, your jaw will drop.
