Xbox360. Went from Sony completely dominating the market with PS2 (155 million devices sold), to Xbox360 and PS3 going head to head (78 vs 78 million). And they didn't do it by leveraging Windows, Office or forcing anybody.
and now look at what the xbone is going to turn into? PS4 is leading the mindshare, while microsoft attempted to use their "strong" position to leverage their device to becomes the center of the living room - which they find out is impossible because they don't actually have a compelling device.
Can't more than agree on that. It's partly because there are no strong positions in an industry as volatile as consoles, so leveraging any perceived strong positions is probably a recipe for disaster.
