[citation][nom]Zebulon Pi[/nom]If IBM had been as vehement as Apple in protecting it's "IBM PC" way back when, can you imagine what the world would look like? No "PC Compatible" machines? 20 different chipmakers, 50 different OSes, 200 different file formats... none of "this" would exist.I need to find the IBM lawyer who decided NOT to sue, and buy that man a beer...[/citation]
Buy yourself a beer, since you made this all up. First, IBM didn't own the processor or operating system, and there was MS-DOS machines that were not completely compatible with the PC (Tandy 2000, for example), and in some way superior.
IBM did enforce patents, and in many cases would make other companies pay up to 5% of the cost of their PC. They also made it almost impossible to clone Microchannel.
So, no, you wouldn't have anywhere near those numbers. You'd have Apple, maybe one or two MS-DOS based machines, until the patents became irrelevant, and then everything would be as it is now.
