Photoshop: Cs3 or Cs4?

I find it difficult to go back to previous versions once I get used to one. CS3/CS4 isn't such a big issue for me, but one of the computers at our studio has CS2 installed which sometimes I have to use if it's for a quick corporate headshot or whatnot and using it actually... infuriates me!

same here, i hate using cs3. I still have it installed because that's the newest version that my scanner will jive with.

One of the main things that jumps at me, is the lack of histogram behind the curves graph. I tend to use curves as a cheap way to access levels too (just leave the line straight).

you have to go into window and select histogram.
