iTerm (via Sourceforge)I had to list iTerm here because I like it a lot, and I use it frequently. It's not my ideal terminal application, however, it is solid and gets the job done. It works well for telnet and ssh connections as well as your standard shell workflows, but it doesn't have an easy serial connection capability that I have found, other than screen.
