One that takes fairly good pictures and doesn't cost an unreasonable amount. That's all I give a damn about. I don't care if it has extra features like video, viewscreen, or if it's small enough to fit in my pocket complete with the provided silk-lined hand-made leather pouch made from the scrotum of 50 starved Ethiopian adolescents.
I currently have a Chameleon XP: "Extreme Photography"
It's a few years old and takes pictures almost ****ty enough to pick out the pixels.
Edit: I'm thinking of the one on the top of
this page.
