Some mixed responses on the itunes store but.....
Twitterific for iPad (free; $4.99 for Pro account) - Definitely the best Twitter app on the iPad so far (pictured above). It works great in portrait and landscape, contextual links conveniently pop out and photos even get special format treatment. No option to upload photos when tweeting, but we're guessing with a lack of a camera, it didn't seem as necessary an addition -- we like to show off our screen captures and saved browsing images, but hey, that's just us. The only deterrent for power users is that you can only view one column at a time, but with lists, saved searches, and all other thread options easily accessible from the leftmost column, we didn't find it too inconvenient whatsoever.
