hmm, aim and fire... is that anything like a "point and shoot"?
Joking aside, look at the Panasonic Lumix DMCFX01S. Its a great p&s camera. It's quick, responsive, and small, 6 megapixels, 6x optical zoom, optical Image Stabilization, and the Leica name on the lens doesn't hurt (admitedly, you're not going to get a phoenominal lens for that price mark, but it's still pretty good).
The Source has got it going for 399.99, so that should fit your budget.
The controls are pretty straight forward.
