3.9 is pretty much 3.5 with bug fixes and some _optional_ crap offered along with it. I seriously don't grasp all the "oh my, 3.9 is so slow" mantra that some people seem stuck with. The only thing that can slow down 3.9 compared to 3.5 is picture.datatype, which is a "fat" (powerpc and m68k) binary in 3.9, but which is also easily replaceable. Anyone with a pimped up 3.1/3.5 install would also replace picture.datatype anyhow.
ah, good to know.
I guess my concern was that one site (amigahistory or some such) stated that a "medium performance" system would have RTG, which I dont have, and likely won't in any near future.
I'll look for a CD then. I've gotten a 3.5 setup and really dig it, but I'd love to check out "the state of the art" as far as 68K goes. This is stuff I never even knew existed back in the day

As far as the optional crap, what all is included in terms of actual functionality?
In other words, what functionality does 3.9 provide over 3.5?
