Trackballs:
Logitech Trackman Marble for Macintosh (P/N 804219-0000) [Don V.
Zahniser]
An ergonomically-designed trackball with 3 mouse buttons
that correspond to the index, middle, and third finger
positions. The thumb moves the trackball (about 1.25"
diameter), which is mounted on the left-hand side of the
assembly. Software is provided for programming the buttons
on the Macintosh, but on the GS, all three buttons act as a
normal mouse button. On a ROM 01, fast mouse speed is fine
for normal use, but slow is better for activities that
require precision. A really nice, comfortable, easy to use
trackball. Does not have a free-wheeling spinning action
as on some larger trackballs. Appears to be immune to dirt
build-up.

Well, there was this really cute little MicroTRAC (by
Microspeed) trackball there, and it sort of followed me
home. It's one of those little thingies that can be used
with laptops, with a total footprint about 2/3 the size of
the mouse that came with my GS. I have it attached to the
side of my keyboard right now. It's a three button mouse -
er, trackball. Left has standard mouse button action,
right is a double-click button, and center (behind the
little ball) is a click-lock button. It's got an LED that
lights up when the mouse button is down (great for those
2am CoPilot sessions ;^). Action on the ball is pretty good
(far better than my defective Kraft), but certainly not as
smooth as the Kensington Expert Mouse that I use on my
Vectra at work. I kinda like it :^)

A quick update on the MicroTRAC -
This little critter has a decided X-Y axis preference; I
think it's because it doesn't have a diagonal idler
bearing. This makes it harder to track from corner to
corner of the screen. OTOH, it is GREAT as a 'mouse' in
AppleWorks, where inadvertant diagonal movement of my mouse
was driving me crazy trying to position the cursor (and
yes, I did play with the mouse sensitivity settings).
