Microsoft officially launched its Surface 2 and Surface Pro 2 tablets on Tuesday morning, stealing a few hours of the spotlight before Apple is expected to announce refreshed versions of the iPad later on Tuesday. Microsoft kicked off with midnight launch parties at several Microsoft Stores, where customers could win several "challenges" and win a chance to be flown to Florida for a special Pitbull concert. Photos from the Westchester, N.Y. launch and the Dadeland Mall in Miami indicate that at least a few people showed up.
