Microsoft Office 2010 is a worthy upgrade for businesses and individual users who need professional-level productivity apps, but it will take some time to get acclimated with the reworked interface. Users looking for bare-bones, dead-simple office software should stick with Google's and other online offerings or continue using older Office versions they have already mastered. The world has changed plenty since Microsoft introduced Office 2007. In that time, Google has become a major player, with its suite of online tools, and even Apple has made inroads with its iWork office suite, though admittedly within a smaller set of computer users. Even with the vast user base of Microsoft Office products, with new competitors in the market, Microsoft Office 2010 needed to be good. Playing catch-up and looking forward simultaneously, Microsoft tries, in Office 2010, to remain (or become) the central hub of your working life, letting you use your PC, smartphone, and the Web to make your projects come together more efficiently.It's true: every application in the suite has been improved and tweaked in an effort to make your busy days more efficient, but you'll need to be ready for a learning curve to get accustomed to Office 2010's changes.
