"TweetDeck and Tweetie are at the top of the Twitter client food chain, respectively holding the number two and three spots after the web (according to these stats). But until now TweetDeck has dominated the Twitter client market without having a mobile presence. Now that they’ve penetrated the mobile market with a darn good iPhone app — released today — and plenty of buzz, TweetDeck has flipped the iPhone hierarchy of Twitter apps upside down. With the new mobile entrant available sans a price a tag (that’s right, it’s free!), we thought we should pit the newbie against the seasoned competitor to see who comes out on top." - Andrew Trinh from Bookmarklet
