As excited as I am for the iPhone, I'm just as excited for Mac OS X Leopard - that's why I have to thank TUAW reader Uros for sending us a link to a big ol' batch of Leopard demo videos posted at Brightcove, a video sharing service. Demoed in the videos are features like Screen Sharing, Cover Flow, Parental Controls, new screensavers and even some interesting new stuff in Preview. Most of this stuff isn't too groundbreaking on the scale of, say, Spaces, but the devil is in the details for me and it's really interesting to see some of the handy new features that unfortunately couldn't make it into Steve's keynotes. For example: Leopard's new Dictionary app can also search Wikipedia, right from within Dictionary itself. If you're interested in seeing more of Leopard in action, these videos might satisfy your appetite - at least until Apple orders them to be taken down, of course.
