Amazon is advertising a product called “Flip,” which appears to be a digital camera with a built-in USB:

Genius - one of the biggest drawbacks of my current camera is that I need a special cord to transfer photos from the camera to a computer.  There’s been a few times at work (or while travelling) where I’ve wanted to transfer the photos but haven’t carried around the cord.

However, an Amazon review notes that it uses two AA batteries instead of the usual  rechargeable battery.  Also, I imagine the quality of the photos and video may not be as high as a standard camera.

Though I won’t buy Flip, I hope it’ll inspire other camera developers to build USB ports into their own cameras.
