I already answered.
My posts have mostly proven your point on phones. But I think Apple dominates in mobile devices.
Sure, people may be able to play music on their Nokia phone, but they do not appear to make MP3 players or netbooks. As far as I am concerned, you have not indicated any other company making smartphones, music players and netbooks.
And Apple clearly is a leader in industrial design.
By your own definition of mobile devices, it's not even close. Nokia cleans Apple's clock.
The Nokia 5800 is the hottest selling MUSIC player in the EU and Asia (you know, 65% of the world's population). They've sold more than 16 million of them, averaging a million units a month, selling neck-in-neck with the iPod Touch (which is the equivalent product in the Apple lineup).
The N900 is a monster of a mobile computer, with a full touchscreen AND an integrated slide-out keyboard. They're doing 100K units a month, not iPad numbers, but then again it's a smaller device, and their bigger, MeeGo based unit will be out later this year.
And as we've seen above, Nokia simply owns the cell phone markets - smart and regular. No contest with anyone else.
Nokia makes phones, music players, and internet appliances (which is what the iPad is). They compete in the same spaces as Apple. And they totally dominate Apple in sales.
But yes, Apple makes things pretty! They just don't sell as many of them as you claim. How you can still believe Apple dominates mobile devices is a mystery...
