yep, wish someone could port Aqua to Linux.
Apple would be on top of that like white on rice.
I have seen pics of YDL running what looked to be Aqua style windows.
All of the colors and widgets are included in the "Liquid" theme, but I can not find a way to make the window title bars look like Aqua windows.
My only beefs with YDL is the fact they are trying to Windowize it with the browser (Konqueror or Nautilus) be the web browser and file browser.
I like KDE better overall, but I find myself using GNOME alot because its Nautilus browser is much faster than KDE's Conqueror.
Also I hate hate hate having to edit config files. Had to edit the /etc/fstab file to make the computer mount my HFS drive.
AS I said, not ready for primetime, but it is well on the way. OS X is still the best out there. But, on an old machine like the one I have it on...Linux is the way to go.
