Leica D-Lux3.
Pricey, but a very good camera except for low-light situations.
It does wide format and has a great wide angle zoom. Great piece of glass makes all the difference, and this camera has the best piece of glass that I could find on a P&S. Honestly, it outshines my Canon 10D in many situations.
If it is outside of your budget, check out the Panasonic Lumix DX2, the same camera and lens except for the firmware and provided software.
