Why would you want to have Open Source software on your computer? Let’s consider a few reasons:
(1) First reason that every one thinks of is that Open Source software is free of cost, well it certainly is about 95% of the time but it can be paid too although the license will be less restrictive. Nevertheless it can save you hundreds of dollars.
(2) Another often overlooked aspect is that you can have full access to the source code of the software. This is a great blessing for someone who needs the ultimate customization.
(3) You can actually help in the development by fixing bugs, releasing your changes to the code (in accordance with the license of course).
(4) They may also offer more features then their commercial counterparts.
With that out of the way, lets get to the fun part and lets save some bucks. I will be giving information on my personal favorites (which would generally mean BETTER) open source replacements. There are however other choices as well, so drop a line or two if our choices differ!
