Go for something in GB, never in MB. I'd go for anything bigger than 4GB. Say... if you can swing two, get a couple of 8GB cards. That'll keep you happy (and the storage capacity is nice too).
I got a Fuji X100 (no S) last year. I like it enough to not feel envious of not having an M9. It does the trick, it's cute and retro-looking. Also, expect some quirks (like with mine, not shooting wide open with the ISO at 100, on aperture priority, on a sunny day. Why? The shutter won't go beyond 1/500th on A. That's it.)... otherwise, it's an enjoyable camera.
Basic leaf shutter related issue.. If your shooting wide open, basic physics related, can't make the leaf shutter open and close fast enough at f2.. Eventually as u stop down, u will finally get to an f stop combination which will allow higher shutter speeds. I remember reading about this someplace, right now can't remember where.
