Linux has gone a long way in the development phase so that it comes very close to all the capabilities of Microsoft Windows. It is usually either free or cheaper than Microsoft products. The software has less problems and more security since it is not a target like Microsoft products.
Ubuntu Linux is the software version that I like best. You can get CD versions or download it from the internet. It has spreadsheets, PDF file viewers, word processing applications, printing capability, and many other Windows-like programs.
The purpose of this website is to discuss worthwhile Linux books. Click on the tabs in the left-side navigation pane to see book reviews or other Linux information. By reading various books and trying out Linux software, you may be so satisfied that you don't care about Microsoft Windows anymore!
