If you have yet to seriously consider switching to GNU/Linux, it is really crucial for safety, security and having control over your own computer, instead of letting Apple or Microsoft decide every little thing you can or can't do on the computer that you supposedly "own"...

Switching to GNU/Linux is not as hard as it seems, and you feel great logging onto your own computer each day, instead of merely getting to borrow your computer from digital landlords like Apple/Microsoft/Google. You can read my story of switching to GNU/Linux, and there are plenty of great tutorials around for how to do it.
