Another interesting note on the apple blogs is that Adobe is set to release CS4 sooooon. The announcement date has been set for September 23, while the actual release date has not. But reading some of the other blogs, it sounds like the release date should be some where around 3-4 weeks after the announcement date.
This is good news. I am still running CS2 and have been meaning to upgrade to CS3. This announcement means to hold off until CS4 comes out. I might as well buy a full version as the upgrades to CS3 and CS4 would be just as much!
