Wait, so Apple shouldn't have been allowed to use its iPod monopoly to gain a foothold in the smartphone market? Or its monopoly of the smartphone market to gain a foothold in the tablet market? Or that Google shouldn't have been allowed to use its internet advertising monopoly to gain a foothold in the mobile device market?
Never mind that the tablet market *is* the PC market (is the laptop market, etc). Or that Microsoft basically invented the tablet market. Or that Windows Vista was going to have an app store but that it was killed because of over-regulation.
Antitrust regulations are there for good reasons. But none of those reasons have anything to do with handicapping successful companies or preventing them from leveraging their strengths to remain relevant in a changing market.
Oh, and it boggles my mind that you think Microsoft should be fined for trying to adapt, while simultaneously you claim that they're failing at it. You don't really think these things through before you post them, do you...
