Wow, fast reply, I barely PM'd you just now.

Uh-oh, half size? I didn't realize there was more than one size... It's what I'd call "normal size", that is - an exact fit for my DSC-P10, and the same size as any other memory stick I've ever seen.

Please define "half size"?

***EDIT***

Ahh, here's a good page: http://www.memorystick.com/en/support/support.html , although I guess you knew this already. Wow, that much more, on that much less card? I guess I shouldn't be amazed.
