I am a retired officer of the belgian army. I started my PC hobby in the 80's with the first Tandy PC with a memory of 64 Kb and a cassetterecorder as external drive. From there I connected a floppydrive (64KB more); Then Windows came out and from then on I gained experience. Finally, as I stated before, I had enough of changing from Windows 3.01 to 97 to 98 to 2000 etc. Same for Office. Each time with the promis for more safety . Finally I had the courage to try Linux, first next to Windows but after a couple of days I decided to pass to Ubuntu. And I do not regret it.
