@lijiansnd you're correct - the ability to pull photos from Flickr or get weather information are not necessarily new features for a digital photo frame but what makes FrameIt unique is that it's a web based service that integrates with lots of different photos storage sites like Flickr, SmugMug, Live Spaces, Live Mesh etc. not to mention information sources for news, weather etc. The service is constantly being updated meaning that the features of your digital photo frame (should) get better over time!
Also the frame in the video above has built in internet connectivity so you don't have to keep it plugged into your computers USB port, and your computer turned on, like the Guitar Boy 2.4" frame needs. The price difference is significant though...
