TeamViewer is free for non-commercial use and let's me control my Samsung netbook with my Lenovo laptop. I have my Samsung hooked up to my stereo system and now I can start Pandora or ClassicsOnline on my Samsung by controlling it with my Lenovo.
I wouldn't have been to do this with Windows Remote Desktop as far as I know given that I have Windows XP Home on the Samsung and Windows 7 Home on the Lenovo.
I could also use TeamViewer to transfer files across computers if I wanted.
dotNetRDF seems like a great open source tool to help me learn more about linked data and it's got a nice tool for running SPARQL queries called SparqlGUI.--------------
