I’ve always thought there couldn’t be any good reason for Twitterific to have such laggy scrolling, and for other iPhone applications to be so convoluted (actually, I’m not quite a fan of Twitterific’s interface either); well, here’s a small guy showing everyone how it’s done.

The interface is simple, everything is where it should be yet every single functionality you can need is there — the interface design is just perfectly prioritized (except for theme switching being buried in the iPhone’s Settings app, which is alway annoying).

Perfectly worth the price. (Well, you could be using Twitter’s mobile web interface, but it’s not nearly as full-featured.)
