Abstract Computing
I love technology! One of the things I've seen a lot lately is Abstract Computing (I can't think of a better way to describe it?)
You can run one or more simulated computers inside your current computer. That's called VirtualPC.
You can connect to a computer in another room and work on it like it's your current machine. That's called Remote Desktops (or Terminal Services).
You can use the same mouse, keyboard and clipboard on more than one machine(even if it's running a different operating system!). That's called Synergy.
Not to mention that you can administer IIS servers and SQL databases for any server from any workstation. I think Active Directory gives us that ability.
Throw a dual monitor into the mix, then it becomes quite a task to remember what computer you're working on! Fun stuff.
