True, CS4 is very old. However, even by today's standards, it was a very costly investment and not all of us who do graphic design have ongoing, full-time positions that make the also-costly upgrades affordable. Adobe KNOWS they have the best design program - that's a given. But their new "subscription" pricing has priced SOME of their customers out of the game. Apple can't be responsible for assuring that every program continues to work when they issue their upgrades; but Adobe could have a LITTLE more consideration for the enormous (for some of us) investment people have made in their S/W and put out SOME effort to keep us up and running. Instead, their attitude is "Too bad, so sad, goodbye!"
