I am a lone developer, developing Web Sites/Apps in PHP. I dont work with anybody, I use a framework so I dont create libraries for my apps (most of the time).

I have read a lot about Version Control and its benefits, but I dont understand how it would benefit somebody like me.

The biggest benefit I can see it having is that if I posted the code on a remote server I could work from anywhere on any computer, but I carry my laptop like I carry my phone so again I dont see much of a reason there.

Can somebody please explain to me in a simple manner the reasons for going with a VCS, and give me some good free ones I should try? Are there any hidden benefits/scenarios that you can think of that may sway me in any direction one way or the other.

Thanks
