How do you paste text then? And there are quite a few applications that 
use the middle button to scroll the visible layer (e.g. gschem), or 
to open a link in a new tab (e.g. Opera, Firefox); very comfortable.
I definitely need the middle button very often each day.

As a side note, I use only "Model M" keyboards even on current PCs 
(although none of my IBM keyboards are labelled "Model M", but 1391403; 
can someone please clarify the origin of this designation?), and the good 
old Logitech M-Series mice (my current office PC has the _serial_ version)
