A friend of mine is the owner of a hosting-company and the last few years he has seen a rise in demand for good Windows-based hosting-solutions. As a consequence of this, he has reworked his provisioning systems both for shared hosts and VPSes to work smoothly with both Linux and Windows to the point that the only difference you will notice is the price-tag. Everything works out of the box. The platform you want, capacity you want, extras, applications etc. And this with no extra manual work for the company. The provisioning system is a massive enterprisey setup with at least 10 servers. I doubt he would have put in all this effort if it weren't for an actual demand in the market. That said (and despite getting free hosting as a "beta-tester" and Windows consultant), I'm going to give AppHarbor a try.
