I'm camera shopping!

I need a new digital camera. Mine still works, but its like a brick, its so damn heavy and not slim at all. And its only 4 megapixels, which sucks considering that now some cameras are up to 10+ megapixels. Plus LK brought his fancy new camera when he came to visit and I noticed how nice it was, and that motivated me to step my game up. Right now I like the Canon Powershots and the Casio Exilim, but I'm still open to suggestions....any ideas or recommendations?
