However, I find slow write times to be unacceptable (check that: unbearable) exactly for the reasons stated above. I've been shooting mostly L/F JPEG, but I've been waiting for the right camera to move to RAW. The X100 doesn't appear to be that camera.
Will you be shooting many frames per second in multiple clips? Seriously, if you are not machine gunning a scene (or trying to swap VFs while its writing), you will not be bothered by the write times.
