Microsoft was a monopoly. They tried to leverage that monopoly by winning a new market. The monopoly was not illegal. The leverage market share in a new market is not illegal. The leveraging a _monopoly_ into a new market share was what they were found guilty of.

Apple has had the tablet in the market for less than a year. Let's see how things work out for a few years before we call them a monopoly, shall we?

I think Apple would be very, very happy to exit 2012 with 75% market share in tablets - the point at which they can't really be called a monopoly anymore.
