Agreed. Tweetie for Mac is my preferred twitter client for Mac. Last I heard, Loren is working on a beta of Tweetie 2 for Mac. I bought it through the MacHeist bundle, so I'm supposed to get access to the beta. I hope the Mac client has lots of features from the iPhone client, as I find the iPhone client is way ahead of the Mac oneDefinitely the official Twitter app. Speaking of it (Tweetie), i hope we see Tweetie 2 for Mac soon!
