2010 or Twenty- Ten?

You would think that with all the problems the world has to face going into this new decade, what to call this year would be a non- issue. But, there's always something to discuss, and apparently what to call this new year is one of the hot topics.
So, is it 'Two thousand and Ten' or 'Twenty- Ten'? It seems the history books want a common name for this year! What do you think it should be called?
