I think so because It has lots of features than 2009 or 2007 office.
Some of the new features are:-
1.Microsoft Office Communicator 2010
2.Microsoft InfoPath 2010
3.Microsoft OneNote 2010
4.Microsoft SharePoint Workspace 2010
5.Microsoft SharePoint Designer 2010.
some other features are also can be seen in powerpoint as well as excel,word, access and outlook.
Do you its the 14th version of Microsoft?
Its costly but in future it will really prove itself that its the best version in Microsoft office world.
Lets hope for the best.
Best of luck
