TeamViewer - Remote Desktop Made Easy

TeamViewer is a software for remotely controlling any PC or Mac over the Internet. It supports Windows, Mac, Linux and Mobile (Android, iOS, Windows Phone 8 and Windows RT, even BlackBerry!). Just install and run the software on both devices, then you can use one to remote control the other via Internet using a pre-generated ID and password. What's more, the software is free for all non-commercial users!

I once tried to use the Windows remote desktop to control my computer through my laptop, but experience is rather frustrating - all that settings, user rights, firewall... Now with this software it just simplifies everything. Another great thing is it makes file transfer between computers comfortable - you can just "ctrl+C" (or right click -> copy) at one computer and "ctrl+V" (right click -> paste) at the other computer.
