Yea, I always have issues with these questions, but this one makes no sense. Contrasting a software company with a hardware company? No, not even that. Comparing an OS with a chip manufacture. Strange.
You know.... You could do the question this way. What would the one company be without the other. In that case, I would say Microsoft would be almost entirely unaffected if Intel were never in business. Intel, on the other hand, would be in tough shape without Microsoft. Still have the OS vs company issue, so.... Just forget it.
@kimjungrules - For what its worth. These are the processors windows HAS run on. Intel, Citrix, ARM, IBM Power PC, HP Itanium, Motorola. The OS core can be run on LOTS of processors with changes and recompile.
