I'm about to get a 20D (my first DSLR). I've read lots of threads about CF card speed. Most essentially say that if you don't shoot big bursts (i.e. enough to fill the buffer), any speed CF card will be fine. I don't shoot big bursts with my film body, and I don't expect to shoot big bursts with my 20D, so this is irrelevant to me. I also don't mind if it takes a few seconds longer for the camera to finish writing to the card, or if it takes a few seconds longer to download the images to my PC (I'm accustomed to scanning in slides/negs, and even the world's slowest CF card will be waaaaaaaaay faster than scanning). But I've also seen a handful of comments that a faster CF card speeds up the viewing of images on the LCD. Should I be concerned about this?
