I work professionally as a software developer with Linux, but the Windows installs at my workplace are quite limited, so my current/working knowledge of Windows is almost nil. At home we have all been happy with this arrangement, and the kids have been using their Nintendos, PS2/3's and mobile phones up until now. However, my oldest kid (12) now wants to play World of Warcraft and League of Legends with his friends. I have spent more hours than I like to admit getting this to work with Wine, with limited success — seems to always fail at the last moment. I considered an Apple machine, but they seem to be quite expensive. So, I am going to bite the bullet, and install Windows 7 on a spare Lenovo T400 laptop, which I estimate will be able to run both Windows 7 and the games in question." Read on for more about the questions this raises, for someone who wants to ensure that a game-focused machine stays secure.
