The huge bonus as I see it is that you can go to any machine anywhere and connect to another computer, without having to worry about opening up the firewall, without having to have laplink or VPN software installed, just anything with a browser.

If you are traveling with a laptop with citrix or a VPN on it and have a tunnel to your PC then that's fine, but if you are just traveling and want to swing by an airport terminal and get hold of something you forgot, then it's great.

It's certainly not the same as using a VPN or Citrix, but it's way easier for what it does.
