Yes.  If you drag mouse-1 inside the current selection you get
drag'n'drop, if you drag mouse-1 anywhere else it marks.

I agree.  I don't have mouse-2 on my laptop.  I can use all GNOME &
KDE applications just fine, but Emacs is almost unusable until I plug
in an external mouse.

The mark/drag behaviour above isn't the only problematic thing in
Emacs if you don't have mouse-2 -- GNOME and KDE have RMB (mouse-3)
menus in input fields which contain "Paste" and "Copy" which are very
useful if you don't have mouse-2.

I would offer to work on this if I had time, but making user
interfaces usable isn't my area of expertise so I'll probably just
waste my time.  Still, as a user I certainly have opinions on how the
application should work though. :-)
