is this some kind of new account, haven't seen you around. Anyway, if you worry about Xbox selling at lose. Let me be clear. A) PS1 and PS2 are selling at lose before Xbox is getting into the market. B) There is NO OEM for PS and Xbox.
Yes, monopoly is bad. Like Nintendo insist on selling console at profit because they can cash more from the consumers. Like how Google only provides turn by turn navigation on Android instead of iPhone. Like how Apple charges cloud storage instead of offering it for free like SkyDrive. If they managed to monopolize the market, just see the impact.
