The dominant reason Fox is so successful is that it is the only conservative-leaning major news network. All the others are liberal. So Fox gets almost all of 50% of the overall market (generally 50% of the population is left and 50% right), whereas all its competitors only get fractions of the other 50%
Are you able to provide some examples of the devices that you refer to as being the same as iPads at lower cost?
When I look at major benchmarks such as Geekbench (where iPad Air gets more than twice as high score as fastest Galaxy Tab), or sophisticated reviews of tablets that contain rich varieties of performance assessments (e.g. Anandtech 1 or 2 where gets similar margin greatest performance than competitors in both general and graphics performance measures), I see iPads generally showing greater performance for the money than any of its major competitors (e.g., Samsung, Google Nexus, Asus, etc).
I'm sure Microsoft has convinced themselves 1000 different ways that this makes great business.
However, the reality is that there will be no future for Windows Phone when the only brand it is associated with in phones is Microsoft. I consider whoever made this decision to be a total idiot. None of the reputation for quality of experience of Apple. None of the fight-the-power hipness of Android. None of the apps of either.
I consider it sad because I actually like Windows Phone a lot and own one. It's got noticably better performance and general quality of experience than Android, and was available at lower price point than Apple. The product was there, for once. Sad to see it fail for different reasons.
