I suspect one really good choice would have been Steve Jobs. 2010 was the year that tablets really took off. 2010 was also the year Apple's market capital exceeded Microsoft's. Perhaps next year, if Apple crosses Exxon Mobil's market cap?

(I realize market cap isn't a great metric in itself, but bringing Apple out of the 90s slump to where it is today, is a feat in itself. Becoming part of our culture and daily life, is quite another.)
