I love my Canon digital elph (SD800). It is small and light and goes everywhere with me.
It is very easy to use - I've even taken pictures and movies one-handed while biking.
I'm quite happy with the photos it takes.
For what it is worth - I have and use 3 other cameras, incuding a Digital SLR and a film SLR, but the S800 is the only one I carry every single day.
