I've tried the update now and it's very very nice.
Although I tend to feel at times that it looks like my old setup for win98
Even the CLI shell looks like a dos prompt, but I guess that's a matter of taste
The menu bar is soooo nice though
All in all Great job!
I wouldn't want to say any of these pre-installed packages are better than the others. ClassicWB, AmigaSYS and AIAB are all good in their own ways. I keep em all side by side.
