I just bought this camera to replace my Powershot A550 that just broke.
So far it's been great!  The zoom on this camera is awesome!  It's my favorite feature.  I'm still trying to figure out the odds and ends to it, but overall, it's terrific!

One of the best things is that it uses AA batteries. It's so nice not to have a camera that uses a special size.  If my batteries start to die while I'm out, I can run into any store and grab some AAs.  That was my favorite thing with the A550, and it's what made us decide to stick to the Powershot again!
