The whole world hates it! It lags as hell with quatro cores and especial in photoshop they put so many things in the wrong place in the wrong time. They changed the positioning of many actions and they put these god damned tabbed windows and the other useless stuff that require OpenGL acceleration.
If CS3 had the rotated canvas would be the ultimate PS available.
Plus they force you to donwload the whole suite to do some specific tasks with all the programs together.
