+1 on the Canon G11
Especially coming from a DSLR. You will have lots of fingertip control, a good menu system, plus a couple of "pre-settable" shooting environments. Like "Aperature, Daylight WB, Raw, Auto Exposure Bracketing". And then you can switch back to Program for P&S.
5X zoom, about 400 shots per battery, Viewfinder (70% and OK - but it gets you close). With the LCD off you can get 1000 shots.
A bit heavy at 16 ounces. Fits easily in a medium hipbelt pouch.
Look also at the Canon S90. Similar features, though not as accessible, at half the weight, half the shots, and no viewfinder.
