Windows hosting will end up being more expensive. And unless a prospect has a definate reason for being hosted on a Windows servers, they will most likely not choose it. There is less support out on the web for Windows servers, as most Linux software is free and open source.
I wouldn't suggest also selling Windows hosting unless you know you'll be able to attract customers for it.
smidwap, I am a developer (ASP, ColdFusion, MS SQL) and my expertise is within windows environment. I plan on selling value added services bundled with hosting that will require a Windows environment. That being said, I also plan to offer basic hosting using a unix/linux server.
