if u want cs4, download the trial version of adobe photoshop cs4 extended from adobe and then add my MSN [email protected] and IM me asking for it to get the full version.
Hehehe, i did it this way too And yeah, workspace wise, much better There is a few more features aswell, haven't really explored them though.
not tht much, its just the interface looks a lil better. but toherwise its similar and adjustment layers can be editted in a panel intead of window .
