Except for one small detail, scrollbars on the Amiga work exactly
like those on the NeXT. (or was that the other way around?)
Difference: clicking in the scrollspace moves the "knob" by the
height (or width) of the knob.  The difference is with the Amiga,
I typically do a click to move a short distance and a drag to
move a long distance.  The NeXT is just the reverse.  Six one,
half a dozen the other I guess.

I always took proportional scrollbars for granted until I
recently started working on a Mac.  If you are going to use up
precious screen space with scroll bars, they should at least
convey as much useful information as possible.  In a text editor,
for example, with a proportional scroll bar you can at a quick
glance not only tell where you are in a document, but how big the
document is.  

It really baffles me why other window systems have not adopted
proportional scroll bars.  It is not like they are a new concept
or something---the Amiga has been using them for about 7 years
now.  (And I seriously doubt Commodore would try to sue anybody
else who used them!)
