Megapixels are a myth. All those point-and-shoot camers all have tiny ass sensors, so getting more MP isn't really worth it, not to mention, unless you're printing 8x10 on a regualr basis or edited and croping, a lot, then forget the higher MP.
I like the Canon G9 and now G10. I am a pro and use them as a point-and-shoot. The GF can use it with ease, and then I have my manual settings.
