There have been a couple of rumors recently that I wanted to comment on. The first is the confusing signals about Windows Phone Tango. The one that had me head-scratching was that Tango would co-exist with Windows Phone 8. That might be true, but when I think through some of the other rumors around both versions I come to a different conclusion. The main thing Tango will introduce is a new “Starter Edition” that not only is targeted at lower end hardware, it has reduced functionality so Microsoft can charge OEMs less for it. Then as Microsoft releases newer versions, such as WP8, those versions will continue to come in a Starter Edition as well as the full product.
The second is a comment that Microsoft hadn’t yet decided on using the Windows 8 core in Windows Phone. I believe they have, but there is a Plan B. Windows Phone 8 has to ship earlier than Windows 8 because of the longer mobile (carrier trial) cycle. So if Windows 8 itself doesn’t stabilize in time the Windows Phone team has kept their code base working on Windows CE as a backup strategy and will ship that. But this indecision can’t last much longer.
Hopefully this will all be clearer after MWC.
