Won't everyone just end up using Opera Mobile/Mini or whatever other mobile browsers become available for Windows Phone 7 instead of the default if it doesn't meet expectations? None of the serious users of the current types of Windows Mobile phones I know use the crippled versions of IE they contain. I know this is supposedly an entirely new idea, I still see this happening.. especially when customers will expect browsers as nice as iOS, Android, WebOS, Maemo, and even newer Blackberries...
