Microsoft today opened its first retail store in home territory through controversial means with an unveiling in the Bellevue Square Mall. Early reports had about 1,000 line up for the event, which saw CEO Steve Ballmer cut the ribbon, but the company once again used the strategy of holding a teen-focused concert to lure an audience into the store. The first 2,000 to enter the store received two free tickets to a Miley Cyrus concert due Saturday, triggering queues the day before that otherwise wouldn't have existed.
