Many people are surprised when, as an IT professional, they ask me for advice with Windows computers and my answer is "I don't know". The fact is that i don't use it that much, because for nearly 6 years now, i've been using exclusively Linux on my home and work desktops. I don't use Microsoft products because Linux completely suits my needs, and when i use my computer i want to do so in freedom.
The products i use to make this possible are:
- Debian GNU/Linux - core operating system distribution
- Mozilla Firefox - web browser
- Mozilla Thunderbird - email client
- GAIM - instant messaging
- OpenOffice.org - word processing, spreadsheet, and presentations
