Your “smartphone” market share numbers are amusing in that if you posted the same thing for iPad, it would own around 90% of every age group.
The hardware differences aren’t nearly as important as the software differences - the iPad has far more software available than its “competitors” (to use the term loosely). Not to mention the fit, finish and friendliness of the iOS itself, which is without peer.
It’s easy to see why Apple stock is at $360/share, and its market cap is now 52% higher than Microsoft’s. It’s now #2 in market cap, behind only Exxon. Bill Gates must be livid. =:-D
If you’re amused by the numbers, complain to Nielsen. Or are they anti Apple too?
