I've been using Terminal Services (AKA 'Remote Desktop') since I started working at Microsoft in 2000. Back then, we were using Windows 2000, natually. After having used the 9x family of Windows since Win 3.1 (and DOS before that), the whole concept of 'TS' seemed pretty incredible. Yes, I'd used similar facilities on other OSes, such as Solaris, but never on Windows.

Windows Server 2008 brings along with it another similar and related breakthrough. It's called RemoteApp. Instead of remoting a whole desktop, it remotes an application. The initial logon process is very similar to Remote Desktop, but after that, you really do have a window that operates just like any other window on your desktop. There are some aspects of 'remote-ness' that leak through, but they are far, far, overpowered by the utility of the feature. Also, you don't need to logon for each window, just once for the machine from which the RemoteApps are remoted.

I've been dogfooding this feature for a while, and I find it incredibly useful and productive when working from home (which I do a fair bit -- like right now). Imagine having a RemoteApp IE window on your desktop that is on your corporate network. You have your regular IE on your desktop that you use to view random web content, and the RemoteApp IE that you use to browse your corporate network. This is super useful for sharepoint sites on your corporate network.

Next step is to convince (A) your CFO to buy a bunch of Windows Server 2008 boxen, and (B) get your admins to turn on this feature.
