This is a heads-up to anyone not on the latest CS5 rev of Photoshop, Creative Suite etc. Henceforward (from CS6), buying an upgrade will only work if you're on the previous version - in marked contrast to the current Adobe upgrade policy that allows upgrades from the last three versions. http://prodesigntools.com/last-chance-to-upgrade-adobe-cs2-cs3-cs4-to-cs5.html Adobe are to offer reductions on upgrades to CS5.5 through the end of this year - but you're pretty well stuck past that point. It'll be interesting to see what the cost of a CS5->CS6 licence is when it comes out. From my own perspective, I've always saved money by skipping every second upgrade, since I've never found single upgrades to be cost justified in terms of new features.
