Linux(Unix) Windows Convergence...
A little bit of history - bear with me......cutting quite a bit of history out here but you will get the point!
In the good old days (pre PC) there were mainframes, these mainly ran prorietory OS, you choose the manufacturer and the OS to suit your application.
It's where the saying "no one ever got sacked for buying IBM" came from, because you could choose a wacky OS... but the sensible Pre-Geeks bought IBM.
In the late 1970's the Digital Computer Company made Unix the front runner with its VAX/VMS Hardware/OS combination. This was further enhanced by the addition of Floating Point Accelerators (FPA).
Then came the PC, with Bill's hijacked OS, MS-DOS.....and the world went PC crazy.
Gradually over time PC's became the dominant partner, but reliability was crap.
MS-DOS was eventually reliable (and is still used in embedded products) but "Windows" - Bill's attempt at short circuiting Apple, was a nightmare.
Years and years of Windows were released until XP.....finally a reliable Windows....
...and guess what. XP is driven by the old VMS team - yes, its got a UNIX base - you won't get MS admitting it, but its true.
And now? Now we have Vista, built by the MS Alpha Team (not the XP guys)... and its not as good as XP? Possibly? But which team is writing Windows 7?
You guessed it.......and why is it being pushed forward by two years?
So, soon the argument is going to be pointless, the world is going to have a UNIX base, Linux/Windows you choose but underneath its UNIX.
