Sony memory can be pricey...parts as well
Tell me about it. Not only pricey but hard to find. Took me forever to find a 512 meg Duo Pro memory stick and even then I had to settle for a 2-week backorder (which was better than the 5-6 weeks elsewhere). And, looking back, it's depressing how happy I was to find it for $185. at Dell. You can get 512 meg CF cards (used by the S400) for a hundred bucks.

Good advice. May as well not have it at all. Most pointless thing I've ever seen on a camera.

Look at video options with sound, preferably 30fps. It chews memory but is a nice option for birthdays, making short clips like pans of scenary etc
That's a tough spec to get on a $400 camera. Canon doesn't seem to list the framerate of the A80 or S400. They just list the sizes (320x240 and 160x120). The 640x480 at 30fps is one of the things that drew me to my Sony. Of course, it'll only fit about 6 minutes of that on a 512 meg card.

After playing with it for a while, I wish Sony had given me more options for video quality. It's got 160x120, highly compressed, 640x480 at 15fps, and 640x480 at 30fps. It's like "crappy", "wow", and "OMG". It'd be nice to have "OK", "decent", and "not bad" between crappy and wow.

You're better with good rechargable AA batteries than a built in battery - you can easily get AAs switched when away from home to keep shooting
Look hard at battery life in reviews
This one's a bit of a tough call. Some cameras have incredible proprietary battery packs that can go all day without recharging. I borrowed my grandpa's G1 for my last vacation and I never saw a low battery indicator. And I filled and dumped his 128 meg card several times each day and used the LCD viewfinder almost exclusively.
OTOH, if the battery pack
doesn't last all day, you're SOL. You'll have to buy an expensive spare proprietary battery then deal with keeping them both charged which either means a charge/swap/charge routine each night with the camera or buying an expensive proprietary charger to charge the second battery.
An argument in favor of AA powered cameras is the rechargeable lithium CRV3 packs that I've started to see. These can be used in many of the 2xAA and 4xAA cameras. You can get a
rechargeable CRV3 with charger at buy.com for about $30. If I hadn't just retired my old Kodak, I'd buy a set.
