Point and Shoot Digital Camera for Mac

Earlier this month, I asked for recommendations from TUAW readers on a nice DSLR camera, and then last week I decided upon the Nikon D70.

This weekend, while visiting my in-laws out on Long Island, I stopped by East Coast Camera in Valley Stream and went ahead and bought the D70. I purchased from a non-internet, real world place, because in such situations you can usually get a few freebies thrown in with the purchase, and I did. So far I love the camera, which is great. However, my wife, also loves the camera, ever since she saw that I could take a series of pictures very quickly with it. She immediately asked if she could take it with her to dance practice (she teaches dance) to take pictures of her students "in action."

My immediate and final answer was "No," and "Never." However, I do have a no-longer-needed Canon PowerShot G1.

So, dear TUAW readers, in order to save my marriage [not really], my question for you is: What's a good point and shoot digital camera for the Mac, preferably small, capable of taking a series of shots in quick succession one upon the other, which can be had for less than $400? Should I just give her the Canon or should I ebay it and get something smaller, cuter, and which will better suit her needs?
