I have been loving Office 2013. SkyDrive is fantastic for keeping my notes and documents automatically synced between my desktop and laptop. While DropBox can do the same thing, it's a bit smoother when it's integrated right into the app. Also I think it looks much nicer than 2010, but that's personal opinion.

You might still be able to download the free preview version from here http://www.microsoft.com/office/preview/en

It should work for 60 days after 2013 came out. It should give you a good idea if you like it or not.
