I think you forget that part of the Osborne effect is that you render your current product obsolete with the announcement of the new product. Android 2.2 still runs new applications and updates (as evidenced by the Galaxy Tab 7 I have right here running Android 2.3.5... running NEW applications that might even have features for newer devices). It's not rendered obsolete by the newer products, in the case of Android. Whereas, Windows Phone 8 applications cannot run in Windows Phone 7 and there was not upgrade path from Windows 7.5 devices which already were only JUST got released recently. Gun. Foot. Shoot-BAM!
