The word is always used with an implied context, yes, but that context is never just 'the present' with all circumstances staying as they are. To call something 'unbeatable' means that there are still variables that can come into play in the contest, but they don't even matter. The victor is already decided even allowing for the most extreme probabilities. For many or most of the items in the list you were replying to, the contest was not over when the crown was lost. The OPs list was intended to show that many companies lost their tremendous advantages in a variety of ways, that the variables are such that the iPad shouldn't be labeled as unbeatable. And of course, no one really believes the iPad is unbeatable in any meaningful sense. It's just hyperbole for being in a dominant position.
