The argument that Windows won because Macintosh was priced at a premium is a dubious argument.
Apple is able to purchase flash memory, processors, and touch screens in bulk. They own Intrinisty and PA Semiconductor.
Apple looks like Walmart on their supply side and looks like Barney's on the retail side. There is no price pressure. They could slash their margins but they don't have to. It's still difficult to find an iPad and iPhone 4. They can't make enough of them.
Secondly, 95% market share is unnatural. It doesn't happen often. Markets look more like GM/Chrysler/Ford or XBox/PlayStation/Wii. I suspect the smartphone market will develop similarly.
And if you want to say that the iPhone will be crushed like the Macintosh was crushed by Windows then it is just as easy to say that Android will be crushed the same way Sun Microsystems and Novell were crushed when Eric Schmidt was there.
