I use logmein almost everyday. It was money well spent, for me. Being in a business environment where everything is filtered its a nice option. Besides I can easily ftp "stuff" to coworkers on the fly my using my home PC.
Streaming video lags it out some. But I can use almost all the apps. I even fired up WoW and was able to login remotely.
Watch out for evil Terra-Tron; He Does not like you!
