So I've been gimping along using Microsoft Office X for Mac, issued in 2001. It generally works okay (and geez, I'm certainly used to it) but Word in particular will often crash when I save a document. I guess it's showing its age. I'm starting to think about transitioning to iWork (because of low cost and good reviews), but wonder whether I should jump now or wait until a possible iWork '10. Any thoughts? Do we have an estimate of possible release date? Do we have any good guesses about whether the upgrades from '09 to '10 would be worth waiting for?
