The only thing I can say is that we are in different parts of the world.
Around me, a lot of people use the iPad to do drawings, animation, audio and video editing where a laptop or workstation is simply not possible because there's no desks / infrastructure to connect/power/store those products.
The macbooks are indeed used more by developers, but as soon as you get into the more 'creative' areas, the iPad + pencil for those kind of things wins big time.
As I said in another reply if you were forthcoming with the fact that you are basing your opinion in a vacuum (your environment) we most likely would have not went in circles. Instead you claimed “the masses” when in fact your area is a tiny percentage of iPad users worldwide.
