You shouldn't. I doubt that they will buy them, they might support them even more to market their Windows Phones, but why would MS buy them? They already have a deal to produce Windows Phones.
MS didn't buy any other pc vendor for the same reason. They want to sell and license the software, without having to build the hardware.
