Good news. I never imagined to buy a "Windows Phone", but if they do that, and provide a good "restore" system (i.e. easy recover of a non-booting phone via USB), I would be glad of using one, so I can avoid traveling with a laptop (e.g. using the phone on hotel TVs with Bluetooth keyboard would be very convenient). I hope Android provide an equivalent thing. For me a simple dual boot of e.g. an Ubuntu read-only image stored in the SD card or similar would be enough for my needs, if MHL/HDMI-Out, USB OTG, and Bluetooth work properly.
