Uhm, they surely meant the other way around?
Practically no one have ever switched OS on a tablet/phone whereas on a laptop you'd certainly expect to be able to run linux.
And what's the point of talking about the price? An x86 windows tablet is the only tablet that is able to run real applications. For those that want that the price is more than justified. Those that don't want that should probably buy an arm + windows RT tablet (which is probably more competitive to the reduced feature set of smartphone-based devices such as android and iOS).
