Adobe are giving away CS2 Creative Suite for Win and Mac. The Adobe page with the links is temporarily overloaded and unavailable, bu the direct download links work and are available here. (URL deleted)
Also note that CS2 versions of other programs are also available!
Moderator edit: it appears that the reporting was in error, from Forbes:
<font color=red>No, You Can't Download Adobe CS2 Applications For Free</font>
"Update: Following a frenzy of Internet activity ? and some confusion ? it appears that Adobe isn?t giving away free copies of Adobe CS2.
Adobe scientist Dov Isaacs clarifies:
On behalf of Adobe Systems Incorporated ?
You have heard wrong! Adobe is absolutely not providing free copies of CS2!
What is true is that Adobe is terminating the activation servers for CS2 and that for existing licensed users of CS2 who need to reinstall their software, copies of CS2 that don?t require activation but do require valid serial numbers are available. (Special serial numbers are provided on the page for each product download.) See forums.adobe.com/thread/1114930.%22
