You should just be able to rotate and remove the retaining ring and 
trackball. Once those are out of the way you can clean the rollers. 
FYI, I had a 280c that exhibited that problem, turns out oneof the 
plastic rollers had disappeared so I bought a replacement assembly for 
$10.

Personally, I have tried both the trackpad and ball for over a month

is faster, but less precise because it tends to roll as I try to 
click.
The one _real_ advantage to the trackball setup on the 230 Duo I use 
is
that there are _two_ click pads, above and below the ball, which means
when my thumb gets tired of clicking, I can use my other fingers (for

licking)

While we're on the subject of trackballs, anybody have any advice on 
how
to open up the trackball assembly itself?

I have a 270c whose trackball seems to have lost its grip, especially 
when
moved vertically -- often it will just spin & spin without grabbing
whatever it is it is supposed to grab. I imagine that it's like a 
desktop
trackball, in that there are little rollers that occasionally get 
gunked
up, as with mice.

Maybe I'm wrong; I have the service manual, but there doesn't seem to 
be
anything specific about how to get into & under the trackball itself 
(as
opposed to removing the assembly as a whole). Thanks,
