Do digital point & shoots use actual electro-mechanical shutters or do they just turn the sensor on and off?

Question by Mere Mortal: Do digital point & shoots use actual electro-mechanical shutters or do they just turn the sensor on and off?
Do you know which digital point & shoot cameras just toggle the sensor on and off to capture the image?

Only the cheap no name cameras have no mechanical shutter, they just scan the sensor, its like a 'screen grab' on a camcorder. Higher quality ones do, you can often hear it working. Its needed to accurately control the light falling on the sensor.

Look into the cameras lens if you can see the sensor it doesn't have a shutter if you can't then it does.

I am gathering info so I can choose a point n shoot camera. Some of you are suggesting that 10 mp is all I need. AND That I need to consider the sensor size. Processor? Help educate me please.
What is "the sensor size" is this what they call sensor resolution? Image processor?
