Either camera would be a good choice.
You can't go wrong either way.
You are really comparing two different types of cameras.
The S410 is considered a point-and-shoot camera because it does not have many manual over-rides.
The A80 is considered an advanced features camera as it has all of the desired manual over-rides. Of course it can be put in Auto mode and will function as a point-and-shoot camera.
Regarding the A80 batteries. You will want to get a set of NiMH batteries and a charger. You can find these for $10 to $25 at Wal-Mart or Radio Shack. Many people prefer the AA batteries because if your rechargable batteries runs out of gas, you can pick up some AA batteries anywhere and finish the day shooting with them.
Many people love the small size of the S410. It easily slips into a pocket. I have a Canon S230 which is the same size as the S410. I carry it on my belt in a small cell phone holster.
I also have a larger digital camera with more features.
That's the answer.....buy both.
Seriously....If you don't "have to have" the features of the A80, then go with the S410. But if you want to do some advanced techniques in photography you will want the A80.

Hi guys, I really do not know which one to buy, I have been thinking about this for awhile, but still cannot make up my mind. What do you guys think? The A80 is good, but I HATE how the batteries are, and the S410, its skinner, with the lithinium batteries which you can recharge, but does not have the modes the A80 has. Please I really need help.
