What digital camera is best?

I've been using my good and old but trusty Olypmus 410 Digital for about 4 years (it was a fab hand-me -down from mom!). It's only 4MP but the images taken are awesome!!! Generally, Olympus cameras are of good quality, comparable to Sony Cybershot and Canon. My uncle owns a Canon IXUS 70 and it's pretty amazing too! I believe that you don't need to spend a lot for a camera especially if you're just gonna use for mere taking pictures. Canon also has this underwater camera (I think it was just with a casing...) as well.
