You are not going to fire the CEO under a year, his WP plan isn't even on the market yet. Elop has at least been 4x faster to actually get things moving on than OPK. Nokia Windows Phones could be out next month already.

OPK had years to finish his "it's not about hardware, but software" and failed horribly.
Also it's not like Elop made these decissions alone, board have agreed to move with the Microsoft plan.
