so far as I can see, new stuff in office 2010 that I'm going to like:
-syncing to skydrive (25gb free).
-office web apps at office.live.com, including onenote ink, in the browser. I tried out the web apps and they're pretty slick, well implemented as far as I can see. I was especially impressed with the way they duplicated onenote in the browser. That couldnt have been easy.
-mini translator -- hover over a word and see its translation.
Great for language learners. Works in onenote and word.
-inking in Word. No need to print out student papers to grade them anymore
Just write on the screen w/ stylus directly in Word and email it back.
we should be getting 2010 sometime in the Fall...
