I've gone the opposite way and have been running Flipbook alot and using it to keep up with interesting twitter and facebook posts rather then visiting either one's sites or apps. I think I'll switch this week and go back to Zite and see how it all fits together. Regarding video formats, I hate having to convert video. It either gets out of sync, loses quality, or just takes up too much time. Since almost anything is available in xVid format, it's nice to just drop a documentary or interview that I didnt' catch right onto the ipad without having to do shit. $2.99 is a great price for this app.
