Flip-Out Touchscreen
We'd take the big, bright AMOLED screen on and double it up: One would flip out and rotate to aid overhead shots, and a touchscreen under it would preview edits and upload images. You could view your source image in the flip-out screen, and then see how in-camera treatments and edits might look before saving or uploading your images. Of course, we'd want full-on integration with Flickr, Facebook, Picasa, YouTube, and other sharing sites.
Style
The ultimate point-and-shoot would have to look good. We'd take the slick, slim, solid-color look of --even the lens is the same color as the camera body--along with Canon's easy controls. All we'd add is a textured grip for easily handling.
