I’ve been using this combination on a daily basis for more than a year now, and I can’t stress enough how really useful it is. I use it both at home and at work, and everything is very easy and – most importantly – absolutely free.
X11 forwarding with SSH
X11 Forwarding with ssh is a wonderful feature which allows you get windows of a remotely started applications shown on your own desktop. For Windows, there are lots of pretty good albeit expensive products like Citrix, GoGlobal and XWin32, which allow you access your remote Unix desktop sessions. But in reality, if you don’t need any sessions but only want to remotely start an application and get a window from it on your desktop, you won’t need any of these expensive products – the easiest will be to use X11 forwarding and Xming.
