How to setup an automatic function?

Why would someone use linux in the first place? I never knew what's so great about it, other than it's free. But everyone likes it, so there must be something I'm missing. Technical stuff maybe? Something windows can't do?
A friend of mine told me things like:
- linux and all the software for it are free.
- no virus, very secure (I don't think this is true. I think there are less linux users, therefore less hackers for it. Also, linux or not, servers get hacked from time to time, its a race against updates)
- easy applications download and installations, just a few commands (thanks, but I prefer navigating to a nice site and click the download button, then execute a beautiful installer, instead of memorizing insane unhuman commands)
