I basically need this only for editing slides in Keynote that contain mathematical expressions.
They kept all of this, including the need to pay for an incremental upgrade, well hidden at the time of purchase. The upgrade to 6.7e (as opposed to 6.9 for windows users) involves a hefty upgrade fee. What I did not appreciate at the time is that I had bought a non-universal application with no upgrade path to intel macs (which appeared 4 years previously) that depended on Rosetta (which no longer exists in 10.9, 10.8, or 10.7).
