One of the biggest news breaks of 2010 went down yesterday in Barcelona at the annual Mobile World Congress.  Microsoft finally unveiled their new mobile platform Windows Phone 7 Series.  While the name may be a mouthful, a successful delivery later this year of what was promised yesterday could amount to the biggest comeback Microsoft has ever taken part in.  Take a look at the video above showcasing Microsoft's unique twist on the mobile experience.  It's far more capable than what we saw on the Zune HD and Microsoft's clearly heading down the right path.  It's so lust-worthy, let's hope they deliver!  RIM, now it's your turn.
