That stinks that it doesn't take xD! I didn't realize that. My Canon has SD so that's what I was shopping for. It's a cool little thing, especially for the price. It's kind of an insurance policy for me. I didn't want to go overboard. Someone else posted on the same thread where I got the original info, about another one that Costco sells. Hang on, let me see if I can find it:

(That's some huge link, no?

Yup, it takes xD but it's more expensive (and double the gigabytes) than mine.
