When we get widespread combined PDA/cellphone/digital cameras (already more-or-less available) this will really take off, I think. What I’d really like is an add-on to Movable Type that would allow you to email a post, with an attached photo, directly to your blog from one of those devices. I’ll bet we’ll see something like that within a year. With luck, even sooner.
