Just been thinking as I sat here, trying to get this Friday over (got in bed 3:00 this morning) reading a book on SBS.

What is "Open-Source" exactly? I realized M$ stuff IS open-source from my definition of it.
Reasons:
1) Anyone can develop an application in nearly any programming language and run it on windows.
2) Allthough M$ to their own implementation of major techonlogies (Say databasing), you can run any of tons of database products of any M$ operating system.
3) Skipping the past, with the .Net framework, anyone can go so far, of creating their own programming language and compliler. The only requirement is that it must confirm with the CLR specs.
4) The .net framework & sdk are FREE. And you don't need ANY ms product you have to pay for (beside your OS of course) to develop applications of any size or complexity.
I guess the list can go on...and further I guess it can go on in both directions...

Just would like to hear what ppl got to say on this one...
