The app fetches for a pricey $1.99 and there is a free trial, but is it worth it? Our initial impression is for a v1.0 app it's pretty rockin' and yeah, we actually bought it. The main thing we like about is its looks: it feels almost like a native Twitter app. It also caches nicely, has threaded conversation views, retweet (old and quote), landscape support, inline pic viewing, Twitpic uploading and more. The UI is real slick and there's "infinite scrolling" so no more "load more" screens.
