Which Camera is best for me?

[Uncle Vanya]

I think I have narrowed my search, for the moment, to these three. Nikpn P1, Sony N1, and Canon S80, and Canon SD 550.I travel, and also plan to use it to take family photos, pet photos, and someday, photos of grandchildren. I'm not much of an artist, but prefer quality and flexibility in what I buy. ANY advice would be greatly appreciated!
