Word has improved "track changes" and commenting. Definitely my favorite changes specific to word. Other than that, it can also embed videos (nice to be able to play a video instead of clicking a link to open a browser and watch the video...) and it can also finally open and edit PDFs.
Seriously though, check out the new tracked changes. Much nicer than before.
Yeah Word does have a few nice new things but I wouldn't say they are worth the price of the upgrade.
The advanced embedded stuff scares me a little. I can see people adding huge videos into a word document and emailing it to 100+ people on a DL. I can see it being abused.
