Best Version of Photoshop to Use?

I was just wondering from everyone's opinion on what the best version of photoshop is. Also what version do you use?
Please post as I am trying to decide on which version to get, i have photoshop 7 on my school computer, but i hate having to get on that computer every time i want to do some photoshopping ^_^

 

Obviously CS4 it's the latest....and has all the things from the previous ones and more.

 

Best can depend on many factors.

To list a few:
-how good your computer is (specs)
-how much you are willing to spend on the software (the best is more) but there is freeware out there, (also illegal cracks, which are ILLEGAL)
-preference (i have used cs3 for that long that moving to cs4 is just pointless for me, i don't need to upgrade so I'm not going to)

The best impo is Photoshop CS3.
I also have photoshop 7 on my school pc and imo its shit lol

 

each to their own.

The most common is cs2, but i use cs4, because i started GFX quite recently, so i didn't find it hard to learn the new interface and all.

 

i use cs3, each version has its own things, cs4 is more for like design and stuff i tink

 

I preffer CS2

CS2+ are very similar anyway

 

Cs2 is very user friendly and easier to use if you're starting gfx.
