Microsoft's Potential "End-around" in Smartphones

With the recent progress of smartphone virtualization using hypervisors like OK Labs (http://www.ok-labs.com/) and Bluestacks (http://bluestacks.com/) that allow a single device to run multiple OS's, smartphone market laggards Microsoft and RIM could, who lack a compelling app store model, have a potential path to get back in the game.  Especially Microsoft, with only around 7% of the smartphone market, but with a much improved Windows Phone 7/Mango interface and seamless integration with office, adding access to the Android app store could be a game changer.  For enterprise users that are still very much tethered to Office and related Microsoft platforms, the ability to easily run work applications and then access the vast number of third party personal productivity and entertainment apps on the Android App Store could be a great thing.  They key will be performance.  Both Bluestacks and OK Labs claim very little performance hit running dual stacks on the same device chipset.  This will have to be backed up if these devices are to become more mainstream in the marketplace.  But certainly the prospect of Microsoft jumping to a 20-30% market share does not look like a pipe dream anymore.  RIM on the other hand may have too deep of a hole to dig out of.  At least we could have more than a two-horse race.
