As a semi-professional graphics designer... I must say that the latest release of CS4 sucks balls and I am wondering if its just me since every review says it kicks ass. Granted there are a few (useless) improvements like GPU rendering (which inherently slowed down the experience for me) Let me list the issues with two of the programs i use frequently - AI and PS Illustrator CS4 This program doesn't work well with spaces AT ALL. Often times if I set it to space 2 or 3, and flip to that space... parts of the right panels are missing. It's a interface graphical glitch which makes the right panels half drawn and sometimes invisible... and click through! (ie the titlebars disappear!) Everytime I switch spaces the left control bar is tinted black as if I don't have the program selected. Using Expose will make the left control bar tinted out again. The font selection menu is none scrollable using the keys and it doesn't show font previews. So I have to click, scroll down the list using my mouse and see it change on the artboard before going back to clicking the menu again... to another font. In Windows I'd leave the menu selected, press down on my key until I found a font that was suitable. Did I also mention Illustrator crashes often on exit? I've been working on a 4x3foot poster in illustrator and whilst it saves the file... it promptly crashes after saving it... forcing me to force quit the app. This has no happened in CS3 ever. Photoshop CS4 (Who designed this piece of crap) Where to begin... expose doesn't work for this program since it's all in tabs (in fact all CS4 programs seem to forget OS X has expose)... also expose to the desktop leaves part of the PS interface showing. Also often times there are invisible windows that you can click on when using expose. The GPU additions make the program SLOWER.. not faster. Zooming in and out is now animated... what on earth was the point of that??? Also swiping the trackpad by accident ROTATES MY CANVAS (!@##$@#). In addition to the silly bugs the application bar now takes up nearly 40px of space... and if you use it in application window mode and full screen it, it fullscreens to your screen! not the visible part between the dock and top menu so most of the PS controls fall behind the dock. Adobe CS4 is probably the biggest sham of a release ever created by Adobe and a huge waste of money. I'm happy to be going back to CS3 and waiting till CS5 gets released in full cocoa flavor.
