"Windows Phone" inherits the baggage of desktop Windows and of Windows Mobile, neither of which is that positive.
To developers, perhaps. To the average user, Windows is what runs on their computer at home. Most people I meet are perfectly happy with Windows, too. So a Windows Phone really isn't a terrible marketing proposition.
Had 3 people ask me if they needed virus protection on a Windows Phone if they bought one. I was really surprised by this, but I guess, given what we drill in people about their Windows PC, I shouldn't be surprised. When I tell them that WP isn't really Windows and they will be fine, all 3 seemed confused. Really a shame since they did a good job of coming up with a different UI.
