First of all let me state here that I’m a huge fan of Panic. Their software is typically well-designed and extremely functional. Transmit 2.0 was the first shareware application I ever bought for OS X and I’ve kept an eye on them ever since. Yesterday Panic released Coda, an application that unites Web Development under one window. While I’d have a hard time abandoning TextMate — it must be my UNIX roots :) — I cannot but praise their work. John Gruber has a pretty good review of the app at Daring Fireball.
