One of the bigger, if expected, events at today’s CES Press Day was the announcement (three times) that AT&T will offer the Microsoft Windows-based Nokia Lumia 900 smart phone. AT&T announced the news Monday morning at a meeting for developers – with a hand from Nokia CEO Stephen Elop and Microsoft CEO Steve Ballmer; Nokia then discussed it at their own event; and then Ballmer discussed the launch again at his keynote Monday night.
