Why use GNU/Linux?

This is pretty much cliché theme, but I will tell you several reasons why I love GNU/Linux.
1. It is making your life soooo much easier, because it has terminal in which you can make lots of things, for which you have to click a thousand times and spent about half an hour in other OSs, with just one line and in short time.
2. It's stable!
3. It's free.
4. Its philosophy is good.
5. Its community is good.
6. It is highly customisable.
7. You don't have to spend money on high performance hardware.
8. It's pretty much safe (against viruses and similar threats).
9. It's good for programming.
10. There are many free and open source programs that you can use with it.
11. Things are usually working out-of-the-box.
There are probably more things, but I can't think of any right now...

Is there something I don't like about it?
Well... some products are less supported to work with Linux and if something is not working out-of-the-box, then it can be a problem sometimes. Usually there are some drivers or workaround on how to get it to work, but sometimes you don't get all features. That is something to be angry with manufacturer of a certain product, not with Linux and its developers (remember, its developers are usually not paid, and it's all about their good will and time to make all those things working). A huge THANKS to THEM!
