Glypo, if Microsoft are so original, then how come their Windows 1.0, 2.0 and 3.0 systems were developed using a license from Apple for the GUI system? The fact that Apple lost the case against MS for taking more than the license allowed does not get away from the fact that almost everything we see on MS systems these days in terms of GUIs emanates from Apple.
Can't argue with the rest of your post as I don't know, but to represent MS as almost independent of Apple's innovations is not the best plan. And, on that note, there is no invention that hasn't relied on something that went before - Bell probably didn't invent the telephone, Gray might have done, but without Faraday neither would have got anywhere near it!
And, back on topic, Macs are still the best personal computer.
