2012 is the year of Ultrabook Touch, not buy Stupid Apple Foxconn product like a Lemmings.
You re developers or idiots consumer?
Back to Wp7, the problem now is only one : Developer Tool in C++ , app quality like Buildin App.
Next problem is ECOSYSTEM, WP7 is only a mobile, iOS is Mp3 player, Mobile and "tablet" .
For this reason Windows 8 kernel and WP kernel must be unified, but the problem is App. W8 work in WIn RT and WP7 is silverlight adn XNA. XNA is not compatible with Windows 8 metrò (ARM) .
