MS... what a sad sad mess in mobile. Just think... that bald headed moron was in charge of a company that makes money hand over fist, sells an operating system that had close to a monopoly and he couldn't come up with a strategy to make MS number one in mobile. He should have been fired in 2008.
Actually, GaGa flubbed a few notes near the end but then did a save... but this is how much they have perfected lip sync technology... make everything pitch perfect and then, at some point in the performance, throw in a few off key or off range notes just to keep everyone guessing. ;-)
