Geez, dude. "Berkley Linux"? If you're gonna spew uncertainties and so forth, ya gotta be more careful. Mac OS-X is a BSD UNIX variant, which pre-dates Linux by decades. BSD is an outstandingly robust operating system. Linux isn't too shabby either, these days.
Windows is something else entirely.
> It was easy to learn how Linux accesses the 'net. I just down loaded the open source Berkley Code and read it.
Two completely different code bases. BSD was prominent in the early 80's, on VAXes and such; Linux didn't get written until the 90's, on i386 PCs.
I can't imagine how you confused those two. Seriously, you completely undermined whatever else you said with that.
I dont know if I would call 13 years 'Decades' ;)
