and in return you have a bunch of shite phones using your OS and ruining your brand
how is it ruining the brand when they are at 70% market share for all computing devices?
having the full spectrum of offerings (low end w/ older proc, lower res screen; all the way up to high end with everything cutting edge) has given Android manufacturers the ability to dominate market share.
Apple is also rumored to be coming up with a lower end iphone to combat this. Its the reason they came out with the ipad mini even though apple swore you would never want a 7" tablet 3 years ago. And swore you would never want a phone screen larger than 3.5" until they released the iphone 5 with a 4" screen (which is still way too small).
