I'd hesitate to put a time estimate like that on their lead in anything. They've had a "decade-long" lead on a lot of things for over a decade. The rest of the market (unfortunately) acts like it's decided not to actually compete directly with them at all, and to chase other segments instead, putting out products that might look kind-of similar but aren't really serious alternatives to most people considering the Apple version of whatever-it-is.
