George, it's 512 mg, so I think it's bigger than the camera storage card. But that's all moot, after all the angst; I discovered that my laptop will go into a different carry-on, so I'm going to take it. The old, old computer case is awkward since you have to take the laptop completely out for security these days (it has a velcro strap), and my not-as-old one is too small to also carry my books and my jewelry case and my camera (you get the picture).

I'll dither the rest of the day now, but I'm used to that. Mark just sits and says "whatever you want to do", which keeps his good health intact.
