I agree with the statement in whole, yet I disagree with the term 'open source'.
"stable and secure open source operating systems is and what it can do".
Yes there are stable ansd yes there are secure open source systems, but Free Open Source Software is what I prefer to see, improve upon ,learn, write and use.
Give the guy credit, Mr. Gates did introduce the Desktop OS to the world. sorta. Now if Mt. Ballmer and others would get in line with SAP. ODD, DFSG, FOSS and others, then it could be a more productive world for every human.
I cannot affor a Mac, I never could, I do use the BSD OS, BSD is in and of its own licensing scheme, wich is close to DFSG but is not quite there. yet.
Mr Dell did pick up on the Ubuntu craze as it washed across the oceans, but they still sell %98 Microsoft pre-bundled with a bunch of other commercial junk, but hey, they are in business to make money, and they do.
IBM almost went pure Java at one time, SUN-OS, but that fell through. Now that Google is encouraging hackers to produce clean code, is a better stack for everyone that uses these Electronic Computational Devices.
Far as MS Office goes, well, it does not go, most all of my clients are on OpenOffice, SUN, or LibreOffice, kinda new on the block but we are working on it.
Can't we all just get along?!
See that is the line of Interoperability that most Corporations are so scared of. It works in the EU. it works in SA, it works in the US, without constant updating, and even some kernel/slices being cut back down to manageable sizes, then we go the way of the Monolithic Kernel Trap.
Proprietary, I love ands hate that at the same time, I love the fact that a patented device can use its own code, I hate that someting sold to the Public is still proprietary. That is like, "Pay me $1,00,000 for the car, here are the keys, but you do not own own and you are not allowed to repair it when it breaks or fails.
That is the predicament we are in now, $800 or more for a box with a sloppy code in it and we are not permitted by EULA to make it work or work better.
I love and hate MS at the same moment, I love what they have accomplished, I love that some people learned and moved on, I hate that they still can accuse a person of a criminal act if some byte of code they used from a 1962 UNIX Manual is copied or redistributed in any way shape or form.
I appreciate that you keep bringing these facts up and in one way keep the people informed that there are alternatives, alternatives that work.
