Yes, I did, as I am one of those individuals, who, always has to have the up-to-date play-thing. Anyway, it is basically the same. Most of the new stuff is on the 3D side, which I have not yet used. I do enjoy a new tool, located within a new sub-menu of the Magic Wand, it is the Quick Selection Tool. It’s a cool idea, and works 90% of the time. Basically, you have a brush you paint over the general area you want selected. It is generally used to select a person from a background, but it is by no means perfect and takes some time to learn corectly, however, if you don’t mind fixing small imperfection in the Marquee, then it’s awesome. Aside from that, the program runs a little bit faster, and handles multipule brushes in your libarey better (it doesn’t lag as much when bringing up the brushes menu) and the new method for tool-bars is pretty cool. Outside of small changes to the GUI and the “behind-the-scenes” stuff, it really isn’t worth the upgrade, unless you can afford it, or, are like myself, and need the lastest version. The RAW plugin is pretty sweet too. Oh and it takes about half the time to save a .psd then it did in CS3. Note: I am on a mac, running OS X 10.5.6, so that might have some stuff to do with my experiences and load times, etc… Did that help any? I can elaborate more if you like.
