I'm looking for a USB-key sized digital camera, preferably 2.5 megapixels or better. Has anyone seen one? I'd like to quickly be able to snap photos no matter where I am and without a big bulky camera. Photo quality doesn't need to be great, this is mostly for silly stuff I see that I want to blog. It would have a built-in USB plug so that the camera could charge from the computer and getting photos off it would be a snap.
