It's beautiful. Coming from CS3 anyway, much smoother to use. I havent seen CS4 or 5 (dont get out much) and it doesnt look like a lot has been added since CS3. They trickle out a little with each upgrade. Unless the many additions are well hidden, doesnt look like many additions to menus etc.
3D extrusions is sweet. Content aware transform is brilliant. Love the dark workspace. Much smoother handling.
Saving the same multi layered file that took 20 seconds in CS3 took about 3 seconds in CS6.
Bastards! They got me. Dangle a free download and now I have to buy one...
