socialleper- As a former denizen of the Computer Manufacturing world, I must offer a slight correction: Bill Gates based ALL his money-making products on other people's work. "MS-DOS" is a modified version of an OS called "CP/M," which Billy bought. "Windows," of course, is the source of the proverb "Anything Apple can do, Microsoft can f*&^ up totally!" (Still true, from what I've seen.)
Apple also adopted technologies that were around in academic/research circles- the mouse, the GIU, &c. But- and I'm not exactly a big fan of Mr. Job's personality- Apple took what they borrowed or adopted and made well-integrated, easy-to-use products. Microsoft merely replicated the former IBM hardware "priesthood" at the software level.
Mr. Gates, as far as I can tell, is still primarily buying up the real innovators. (And MS Windows is still a giant kludge-pile!) Apple, well, we'll see. Mr. Gates is also a leading funder of the effort to destroy public education and voucher-ize everything, a singularly bad idea which has already been proven a miserable failure. But then, Billy G. could, from his very own bank account, single-handedly eliminate poverty in the US overnight!
Not that he's going to- he's too profoundly ignorant to realize that his kind of economy is leading to collapse. Funny how damn stupid some of these "innovators" can be in the real world...
Pardon my rant! But, to torture your analogy a wee bit further, Bill Gates is sort of the Michael Bolton of software- taking other's hits and selling his half-*%%^d versions to the masses. Being creative is maybe not the only thing that can't be taught.
