Let's begin with the more the merrier. Windows 8 is growing faster and faster and there are a lot of (old) users who have a Windows 8 phone. Advertisers will not be happy that there advertisments are not shown to Windows 8 public and also alot of business users have WP8, though at the moment they CANNOT FEED THE WAZE, the most important thing of Waze is feeding it, so create the damn app. If neccesary put a 'Donate for WP8' button on the homepage!

And the Waze maps will get even better!

Thanks that's it
