Amazon is the one that continues to amaze me. People forget the original pitch to investors was _LOSE_ money for 5 years until they either drove competitors out of business, or became the single largest e-commerce provider. I've never understood how this was legal. It seems like the definition of 'anti-competitive' and 'predatory'? If Microsoft gave a free computer with every purchase of windows, and could afford to continue the practice until Apple, Dell, etc. went bankrupt - would that be ok ?
