It already has USB and theoretically could use a USB-attached camera. The problem is, the iPad-to-USB adapter is something more you have to carry in addition to the svelte iPad and I would worry about inadvertently damaging the iPad connector on the iPad with the (relatively) big adapter. Adding a USB-attached camera is even worse: two more things to carry plus a cord to add leverage for stressing the adapter. Tethering a peripheral (e.g. camera) via bluetooth or WiFi would get around the adapter part, but it still is an ugly solution. I agree with Tim, Apple's target audience isn't me, it isn't him, and it probably isn't most of the people on HN. It is consumers, not creators.
