I think you are not very clear on the meaning of the word disrupt:
interrupt (an event, activity, or process) by causing a disturbance or problem: a rail strike that could disrupt both passenger and freight service.
a disruptive product is a product that breaks with what was before and changes the course of its class of products.
It relates to market share only insofar that it needs enough share of its market to make an impact on it, which is not necessarily a majority.
Now, I think it’s a bit silly trying to say that mobile phones/smartphones/pocketable computers didn’t change after the introduction of the iPhone (see also link below by alanh: http://www.tekgadg.com/storage/Android_before_after_iphone_t..., or check how many phones with and without keys are available today, or the success of the “app store” model).
