iPhoto: New to iPhoto this around is "Events," which promises to let you more easily organize your photo albums, and the .Mac Web Gallery, which'll let you publish and share your photos on the web, with other folks also able to contribute to it. What's more, you'll also be able to send photos to the gallery directly from your iPhone, and sync up your iPhone with photos already in the gallery.
iMovie: Described as a "whole new app," iMovie looks to have taken on some increasingly iPhoto-like characteristics, with it now now being touted as "one library for all your video." It'll let you work in resolutions "higher res than DVD" and, as with iPhoto, you'll be able to share those videos on your .Mac Web Gallery. It'll also encode and upload directly to YouTube and, of course, tailor videos for your iPod, iPhone, or Apple TV.
