And boot times... and shutdown times.. and the ability to create custom screenmodes of any resolution / colour depth... and being able to mount / read different media or media from other from other platforms simply by installing a filesystem and / or writing a mountlist...
Don't forget double click to front
and
The ability to leave a window behind other windows, but still have the focus on that window in back (i.e. being able to type in a window without having it automatically pop to the front when you click on it). What I wouldn't give to have this ability on Win2000 at work.
Just a couple of my favorite little Amiga features.
