why not consider the market a bit, sony makes more products than just the ps2, they got their share of home entertainment, car audio, portable audio and video, even computers.
microsoft does mainly what, software, windows and office programs.(they also have mice and keyboards, and gamepads and such, but thats a small part of what they produce)
when you think about it, sony SHOULD be making more, because they sell a lot of products around the world, but they have more competition than microsoft does, right? you go to buy a tv, there are at least 10 brands to choose from, but if you are in need of a new operating system, most like, you\'re going to choose windows, right? the computer industry grew a lot during the start of microsoft (and i think they had a lot to do with it), so they benefited a lot from it (some say, "monopolized").
well, thats my $0.02 cents.
