I have Linux Ubuntu OS on my computer. It has many advantages. It is hard to catch virus on Ubuntu, Linux is open source project. It mean that developers believe in security of their OS ,because they show to people source code of Linux.
Linux is more fast . First of them, I install it on my computer. because it had a low speed of work on Windows 7. Ubuntu solved this problem.
Linux has a small size of programs relative to Windows. It is free, you can change all in this OS. It is full controlled by user.
Also Linux has built-in free tools (for example archiver, ssh for connection with server from terminal, USB flash drive launch utility, etc,
It have not unnecessary files and programs like Windows. Also it has a small size.
It is post on my site, where I describe my first impression about Linux after launching.
