Good Question!

I guess so many Linux related websites start with assumption that if you are there you want to use Linux. So, the explanation why to use Linux is given like manuals are written - from the point of experience of someone fully familiar with the system in question.

Reason to use Linux could range from

• distrust of big, commercial business to
• altruistic motives of wanting to support Open Source and the generosity of people involved in developing it.
• It could range from saving money on software to
• plainly being legal in all the packages you are using on your computer.

There are some more reasons like

• easy maintenance,
• easy updating and upgrading (most of the time)
• easy access to software packages
• and so on .... (just browse around for more good reasons - and have a look here) ....

For us using Linux was partially driven by the need to develop websites and the need to have a development environment on our network - a "localhost". Under Windows this is possible, but slow and tiresome.

But, 'my Windows is working fine ....'

... sure, then leave it there. Eventually you might want to think about Linux again in relation to option 4. under a previous note written here - Linux & Windows - dual boot or why not? -

You are absolutely right - if your Windows is working for you - well, or Apple for that matter, - you will not need to spend any time thinking about Linux.
