Now imagine your misery when you forgot the CFE reader at home and you have the time to review and edit but you can't.
I'm sure most of us are more likely to forget to bring the CFE reader than the camera or the laptop. I'd love to see laptops have CFE slots built-in, but I don't see it happening. As long as the camera and laptop have SD slots, why would you bring something extraneous?
I understand that.
I went to photograph an annular eclipse back in 2012. I brought the camera and the tripod.
I did not bring the actual plate that attaches the camera to the tripod. I thus didn't get even one usable picture.
