Its using Skype so you'll need install Skype but on the plus side, it works with all Skype versions on Windows / Mac / Linux, and has history log going back 2 weeks (unlike IRC when you log off you dont get the messages you miss). Should also work with Skype for Mobile Phones.

Personally, I prefer the version 3.x generation of Skype for Windows. Its smaller, more configurable, takes up less screen space and memory. If you're running XP or Vista, then version 3.8 is your best choice. If you're on Windows 7, then version 3.6 will run the best. Theres not much difference between the two versions.
Version 3.8:
