Yes, I am, and so are many others.

Ahh, they discontinued their pointing device products for Macintosh. 
Bummer.

Are you sure?  If it's recognized as a two-button mouse, it should
work.  I think the second button's not configured to do anything useful
under your X set-up.  Consult your window manager's man pages for how to
write the "rc" file.

I borrowed a Kensington Thinking Mouse and tested it on NetBSD/mac68k. 
It showed up as a four-button mouse as it should, and I could use three
buttons (the fourth button's not configured to do anything useful under
my fvwm set-up ;-)

Other multi-button relative pointing devices supported under
NetBSD/mac68k include Mouse Systems A3 Mouse, MicroSpeed MacMouse
Deluxe, Contour Mouse (recently added to -current), and Alps GlidePoint.

Hope it helps,
