It's getting harder and harder to pick a smartphone, with options like iPhone OS, WebOS, Android, and Windows Mobile making the choosing difficult. Life would be easier if you could pick two, and that's what virtualization giant VMware is working on, the ability to run dual OSes in one smartphone. The company already has Android/WinMo and other prototypes running, but phones featuring the tech now aren't expected to hit market until 2012 -- a big delay from the earlier indications of a release this year. Those prototypes rely on ugly boot menus, whereas the vision for this tech would see users switching between environments on the fly, taking and making calls in either whilst juggling chainsaws and dazzling their friends. The company pledges it'll be a seamless experience, but we're doubtful given how even stepping out of HTC's SenseUI into the OS below can occasionally result in mild nausea. The bigger question is who would want this, and it's easy to think the answer is "basically nobody," but picture the poor corporate souls who must carry one phone for work and another for play. This tech could finally let them ditch that holster, and wouldn't the world be a better place then?
