2. If the Internet is what most interests you
I dare to say that web browsing is much better in Linux than in Windows. Because in the free operating system will find all browsers without problems and security / privacy will be better regulated. If you are using Skype to communicate at work or with family, no problem. It is available for Linux, as well as tools useful as Pidgin to connect many messaging accounts as Messenger, Hangout, Skype itself and many more. I assure you that Linux and the Internet get along very well.
