Clever utilities are what really get my mouse twitching. In the age of the connected home, more of these devices are disconnected from one another. I have a keyboard and mouse for eight PC's in my home, 3 of which are HTPCs. The HTCPs in my home all are capable of using a Logitech Harmony Remote control and all are currently using a Rocketfish Bluetooth Keyboard and Mouse Combo, but it still is a bit cumbersome. Instead of having tons of remote controls on my coffee table, I have a Harmony Remote, a laptop, and my Rocketfish Bluetooth Keyboard and Mouse. Well, recently, Microsoft's Garage Program featured an application created to help alleviate the need for multiple mice and keyboards for multiple computers.  The application is called Mouse Without Borders.
