If forced to choose a long-term position I would short Apple.
This is because of its P/E ratio of 14.3. That's not particularly high, but it means it would take 14.3 years of earnings at the current level for Apple to repay you the price you paid for a share. That's a long time for a competitor to kill the iPhone and/or iPad and along with it app store revenue.
People are not tied in with Apple products like they have been with Microsoft products over the last couple of decades. It's mostly a matter of personal preference if someone wants to pick up a HTC or Galaxy instead of an iPhone or iPad; the same can't be said of MS Windows or MS Office (although Ubuntu and open-source have started to change that more recently).
So yes, I think 14 years is plenty of time for Apple to lose market share to competitors. They can't bully their competitors with patent infringement lawsuits forever. Today they sued Samsung for using a swiping button to unlock the phone -- that's pretty desperate and shows Apple's edge is constantly being challenged. If they lose half the market share to a competitor's product -- totally feasible given the pace of its competitors -- it could half its earnings and double its P/E ratio. That would make the company look very expensive very quickly.
