Ken, I don't have one, but I've seen the full-sized model put through a sales demonstration. I was impressed at what it could do, but there was no software/app on it to perform photo editing that I use. Maybe there will be, but even if there were, I prefer to do my photo editing on a much larger display. I have a Macbook Pro 13-inch model, and I only use that for editing if it is the only option, like if I'm still on the road and need to review and edit shots before I get home. The iPad is a great tool to use as a display for a quick look in the field, but that is as far as I'd want to use it for.
