I have just realized I have been using Debian as my main operating system for 4 years now. I was using Pardus 2008 before. I moved to Debian after getting frustrated with some packaging issues and I never looked back.
Debian is stable, desktop ready, supports a wide range of hardware and has thousands of packages in its repository.
If you are still a Window$ user and have no idea what I am talking about. This page explains major differences between Linux and Window$. Debian/Linux is free software, you can just install and start using it.
If you have tried Linux before, especially Debian, and have given up for this or that reason, feel free to share your experience in the comments. Maybe there is a practical solution.
If you have any questions, suggestions or corrections feel free to drop me a line.
