We are narrowing down our choice for a digital camera to:
Pentax S5I
Sony DSCW5
Sony DSC T33

Does anyone have any advice for us?  Would appreciate it.
We will be using it mostly for pics of grandkids, their events, and scenery.

Oh, and the easier the better really....as in "point and shoot".

Second question:

Is it worth going up to 7.0 megapixels?  Or should we stay at the 5.0?
