Panic Software, now FTP-Shirts
I have been using Transmit (now version 2.6.2) since its 1.x release back in the day. I have seen it improve over the past years and I have to say that its the best FTP app for OSX out there. I love the Your Stuff/Their Stuff file management paradigm. Transmit also contains some little known features such as chmod file permissions access all thru info windows and pulldowns.
At MacWorldSF 2005 this year Panic released an innovative and hip apparel line of shirts with Mac related icons and imagery. I am truly at a loss to decide which shirt to get, as I love them ALL. You should check out the shirts, but also, if you have not used Transmit or any of their other award winning software, you should def download and check them out!
