Canon IXUS.. i've used tons of point and shoot digicams over the past 5 years and in my opinion Canon make the best... the IXUS is tiny, well built (magnesium alloy), huge 2" screen, super fast, takes stunning photos and can be operated with only 2 buttons (one to turn it on, one to take the shot)

it doesn't get easier than that... plus it's so small it can go into a pocket and not even be noticed
