No. Don't. Stay with what you know. When it comes to printing assignments on other computers (such as through a flashdrive/CD), a 2007 format is not reverse compatible. So...at the last minute, you'll find yourself with a 2007 doc and not a computer with a 2007 Word to view it on! You can make it so that your files save as 97, but still...
I also believe navigating through the new Word is difficult...graphics are also a bit 'simpler' when you don't want them to be. I say stick with what you know.
