One of the trends at CES this year was vendors adding a ton of features and functions to the photo viewing capabilities of their digital cameras, including slideshows, transitions, in-camera editing, and more.  This is a major reason why Kodak's latest EasyShare cameras come with a tilted dock, so you can view images right from the dock. PC Mag photo analyst Terry Sullivan has a great run down on the best camera-based photo viewers here.

Of course, for any camera to be useful as a photo-viewer it needs to have a 2.5-inch or larger screen, but those are pretty common these days, even among ultracompact cameras. I expect to see a lot more of these coming out at PMA in a few weeks.
