Twitteriffic on the iPad is straight-up elegant and clean. Although it's not quite the powerhouse of Twitter mania that is Tweetdeck on iPad, it makes up for it by having a nicer and more intuitive layout.
In portrait mode, you get a large list of tweets, but the real excitement comes in landscape. Twitteriffic uses the now-familiar setup of a list of options on the left, the main window on the right. Your options are simple and straightfoward - viewing recent tweet, messages, direct messages, favorites, a search bar, and so on. I'm especially happy to see lists on the sidebar - that's a feature that's been lacking on many other Twitter clients. The app offers a $4.99 in-app purchase to enable multiple accounts and eliminating ads. Twitteriffic also does a great job with links - photos appear in a small pop-up and web-links appear in a large pop-up browser that's very usable. Tapping a profile brings up an iPhone-style pop-up that lets you browse that user's tweets.
I do sort of wish the lefthand bar was customizable - I'd rather see multiple accounts listed there rather than Twitter trends. You also can't change accounts on an active tweet you're writing - instead you have to back out of one account and into another.
