Call me a stick in the mud, but I'm not wowed. To those bitching about those of us bitching about the looks: well, what else are we gonna talk about? These ARE only screenshots! No one who has a 4.0 beta on their hot little machines is talking performance, so we're going with what we've been given. In this case, an OS that looks like yesterday's news! Ignoring the (naturally) changable colors, not a lot differentiates this visually from the previous OS version. I read a comment in another topic that some folks thought it looked like an '80s Mac GUI, and that's a good summation. The Mac has moved on to a much more aesthetically pleasing interface. So has Windoze. One of the niceties of XP is the way-shway new look of the interface. Sure, you could change back to the plain ol' Windoze look, but why would you want to? Select the silver and not the horribly clashing blue 'n green version, and you have a sleek, professional interface that looks fresh and modern. Hyperion should consult with a couple guys from Amiga.org. From yet another 4.0 screenshot topic, I surfed to some VERY impressive GUI mock-ups that really freshen the look of the OS while still being definably Amiga.
Then again, from my devious little mind comes the thought that maybe they're just gonna let the look and feel of this interim/upgrade OS hang, leaving it to the forth-coming multi-platform 5.0 to wow us. After all, why knock people out with the small step when you can wait and do it with the giant leap? :-D
