I've been using this software for almost a year, and it's simply made my days easier.
Desktop Rover is a software that allow me to control up to 32 computers or my pocket PC by my only single keyboard and mouse.

How to use ?
For computers, verify that each machine is connected by TCP/IP, or local area network. Install the software on both sides, and turn it on. Then, set the group configuration to tell the software where is the position of other computers.
And easily and amazingly, you can move your mouse to both monitors, and type any words with single keyboard on both computers, without any flicker !!

I've been using desktop rover for my Pocket PC, all I have to do is put it in its cradle so its connected with my PC, and then install the software, turn it on, set the configuration of its position, and easily, I can reply all SMSs, browse my Pocket PC by using my mouse and Keyboard so I don't have to move away from my screen.
