For those Mac OS/X users out there I wanted to give a quick shout out for a very nice terminal replacement tool: iterm for osx. For some time there have been a couple of things that bugged me about the OS/X terminal program. First, there is no tabbed interface, all the terminal windows are separate windows. Now its easy to move between these windows with the keyboard, but it is still a bit of pain to get things arranged properly. The other thing is there is no middle button paste like you get with Solaris or Linux. In those Unix implementations, you can highlight text in a terminal window, then use the middle mouse button or scroll wheel to paste that text.

iTerm gives you both of those features, its free and open source. Check it out if you have the chance.
