i dont know if id go as far as saying that windows rocks but i would say that computers would be nowhere where they are today withough microsoft and intel.
windows has alot of problems most due to its popularity (everyone wants to run in on all kinds of goofy hardware, and hackers dont bother with unpopular os being 2 reasons)
and intel cpus have poroblems mostly due to backwards compatibility. but all in all both companies have reseased products that have been useful for millions of people and have constantly pushed the state of the art.
commodore pushed technology twice with the 1000 and the 3000. aga in 92 was only a minor push.
