I do a lot of creative work on paper, including a lot of paper prototyping for web applications. Those prototypes often involve lots of post-its and cut up index cards and such, all of which get shuffled around to fake interaction. Even if I wanted to save the scraps, it’s a big effort to reassemble the paper prototype.

So a digital camera is great. It’s less fuss than a scanner, and I can import stuff into iPhoto or and then into all sorts of other apps. The results aren’t perfect, but they are good enough. I pull the pictures into omnigraffle and draw on top of them if I need to clean things up.
