I have been reviewing a lot of remote desktop applications and have chosen Splashtop. It costs me $99 a year and supports up to 10 PC's. The security is strong, it seemed a little harder to install but after my second setup, it's easy. I also think Slashtop is easy to use and I'm glad I had the opportunity to test it! Go take a look and see what you think...
I would NEVER suggest GoToMyPc (now owned by LogMeIn)!
