T2 Remote Touch is a little like Remote Desktop / RDP / Terminal Services, however you'll get quick control of your computer from your phone whilst still being able to see the computer screen. I've tried it out and the drag-and-drop screen navigation along with the quick overview and easy setup make it a very cool free tool.
This may prove useful to anyone doing presentations or remotely controlling your computer (providing you map through the ports etc) when you're away from home. It's free and is being constantly developed by Sanjay Thomas.
