Admittedly I'm a Luddite when it comes to tiny, expensive electronic toys; I never see the point and I hate carrying yet more crap around (plus they always make them so droppable. WHY WOULD YOU MAKE A THREE-HUNDRED DOLLAR CELLPHONE SLIPPERY?).
But it's with an extra jaundiced eye that I read a breathless review of the Groqit. It's tiny! It scans yer stuff! It keeps you from buying yet another copy of Steel Magnolias!
It's also already been done.
