But what you're are saying.. is that I should be looking for a camera thats good in low light?
EDIT: do you know when the PowerShot SX20 IS will be available in Canada?
If I took a lot of concert shots, or low light photos, a camera that is good in low light is a must, imho, for all the reasons stated elsewhere in this thread. DSLRs are probably the best but they are big, bulky and expensive. In some venues, a DSLR may not even be allowed inside.
So, if you're looking for an all-in-one camera, the best performance will be from compacts that have a larger sensor and/or a faster lens. All digital cameras will perform well in good light.
No digital camera has it "all" so get one with the features you need most.
Another new camera which looks interesting is the Pany FZ38:
