I got in the Eyemodule 2 for review today. I like how the camera is angled slightly and that there is a lens cover.
If you know how to use the original Eyemodule there's not much new software-wise with the exception of full color and thumbnails.
Eyecontact now has color thumbnails (current Eyemodule users can get an updated version from Eyemodule.com) that is a very handy application to have. I'd probably use Eyecontact as an AddressBook replacement if I didn't have to send the Eyemodule 2 back.
As for pictures, good lighting is still important. Expect the full review sometime next week.
