I don't really care what it looks like so long as all the buttons are in the right places. I still haven't gotten over how badly designed the HD toolbox is in those preliminary screenshots. Getting a non-techie to use an app like that is equivalent to torture, regardless of how ugly or pretty it is.
As for the ReAction vs MUI war, I tend to think there aren't any good independent GUI toolkits out there. That, and MUI is slow as a dog under WinUAE on my Athlon 2600+! I haven't used ReAction. I tend to limit my WinUAE sessions to old games these days.
@RedFox: Hey, I have that picture as a 20x30 poster on my wall! Just thought I'd share. :-D
