Because, unlike land-line phones, a cellular phone is a complex device that is an integral part of the system. A buggy or hacked radio software can potentially disrupt service to many other paying customers. It needs to be tightly controlled to assure network availability for everyone. Therefore every phone needs to undergo an expensive battery of tests and certification.

Therefore these phones are actully quite expensive. In order to get the price down to a level to attract the most customers they have to be subsidized. Therefore, you have to sign a contract promising to stick with them for some amount of time to cover that cost.

But you can also pay full price for a phone and get a monthly service plan from most carriers. Many people overlook this.

You can also, in fact, buy a GSM or CDMA modem (only) and attach it to a PC (or TI-89) by serial or USB, add some custom software, and make a smart phone out of it. It won't be very compact, however. Getting all that into one hand-held device is not so easy either.

Modern smart phones, like the G1, actually have two CPUs in them, one for the apps and interface and one for the radio interface. The radio CPU and memory are isolated by hardware.

However, there is growing concern in the industry about security related to hypervisors, and how that can undermine the security (file access permissions,etc.) of the guest OS. Therefore there is a trend to use "bare metal" hypervisors to better secure the whole system. Now, running Windows is the opposite of that. Indeed, it doesn't make any sense, especially considering MSs security track record.

In addition, their driver is about 22,000 lines of code! The existing paravirtualization code (that works with VMware also) is only about 6000 lines as far as I can tell. What exactly is IN that MS driver?

Actually, modern journalism is about profit. A headline and a few sound-bites are all that is required to bring people to look at the advertisements on the page around the arcticle, or see the commercial. Some of us, at least, expect more. But we don't get it, and they don't care as long as they get the advertisement revenue. It's all about filling pages with "stuff" to attract some eyeballs.
