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.<p>Adding a USB-attached camera is even worse: <i>two</i> more things to carry plus a cord to add leverage for stressing the adapter.<p>Tethering a peripheral (e.g. camera) via bluetooth or WiFi would get around the adapter part, but it still is an ugly solution.<p>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.
