I have been using a track ball IIRC since Logitech had the white simi
round unit with the little blue ball that tolled wheels. That ball was
operated with your right thumb. I only had one mouse prior to that
which was in the 80's before a mouse was standard equipment.
I never never never could get use to the finger operated track ball.
The thumb operated track ball was instantly intuitive for me 20+ years ago.
I can see how the finger tip operated track balls might be more
difficult to get used to.
My number one reason is so that I don't have to move my hand all over my
desk when panning a drawing or moving the cursor from one point to
another in the screen.
I can orbit and pan and zoom in/out on my drawings without moving my
hand or mouse.
For some people the track ball is as difficult to master as is the mouse
is to me. I think the thumb track ball might be easier for you, I would
go back to a mouse vs. a finger operated ball.
The Thinkpad line of laptops has a "touch point" or some other goofy
name. It's the red thing in the corner of the g, h, and b keys. It
mostly stays out of the way, but it's far superior to the track pads most
laptops are saddled with. After a few hours of mouse-heavy activity,
like Sketchup, my hand isn't aching and my finger isn't raw.
It did take a bit of getting used to, but it's worth it.
How long have you had that M570?
Now that I have asked, ;~) I am going to tell you how to fix it when it
quits working properly. I am on my 3rd in 2 years, Logitech has
replaced 2 units without requesting a return.
My problem has been with the center click button, this center click is a
big time saver in Sketchup for orbiting while panning. Anyway I could
hear and feel the click but the orbit command would not engage unless I
pressed even harder after hearing the click and then some times having
to hold down the wheel and wiggle it. The cursor would not go from a
pointer arrow to an orbit icon. A real PIA.
After getting the second replacement I decided to open up the one with
the problem. Both had the same problem BTW.
There are "5" screws on the bottom and inside that have to be removed
to open the unit. One screw is obvious just under the ball on the
bottom. 3 more screws are under the rubber pads opposite the ball and
at the far long ends. The 5th screw is under the battery label at the
1.5v lettering. Poke a hole through the diagram label at that point to
find the screw. Then pull the bottom half away from the top half.
Inside you have a small square switch with a round button, flood that
switch with electrical cleaner and or any other switches that may be
giving you trouble. Thoroughly blow dry the assembly, I used compressed
air and reassembled. Works like new again.
I have tried several trackballs, and none felt right. They were much
harder for me to position the cursor accurately than with a decent
mouse. It might be OK for newsgroups & Email with more practice but
they were useless for Eagle (Circuit board layout) ot LTSpice (Circuit
simulation) Forget doing graphics with GIMP or another graphics
I plugged it in to edit this reply. After a week my thumb dexterity is
improving. I've been using the end of my thumb for coarse motion and
the joint or middle pad to put the cursor between letters.
I just noticed that I can position the cursor more precisely with my
clumsier left hand on this Dell Latitude's touchpad than with my right
hand on either the trackball or the mouse. The touchpad resolves 9
separate cursor positions across a lower case 'w'. I'm still much
quicker with the mouse though.

Put your hands on a Logitech M570. it rests under my hand as my hand
naturally would rest on the desk surface. Fingers only do the clicking
as they would with a regular mouse. Your thumb moves the ball, which it
Michael, I did notice the deterioration right from the start. So
what's your point? Obviously, being such a cheap plastic membrane, the
deterioration just kept on. I suppose I could have 'sprayed' a sealer
coating over the membrane switch or RTV'd it or put that PCB gunk on
it to preserve the integrity of whatever seal the manufacturer was
seeking, but come on, this was a cheap microwave.
I have a 20+ year old JC Penny microwave oven with a membrane
keyboard that don't show any wear. It would have been junked long ago,
if the keypad was damaged. It's in storage at the moment because it's
too tall to sit on the kitchen counter. It will be put back in the
kitchen after the handicap modifications are finished. IN the meantime
I've had two smaller microwaves fail. A Samsung had the controller fail,
and a brand new Westinghouse failed with less than five minutes use and
the power cord was so hot I couldn't touch it. A real POS. Right now I
am using a stainless steel piece of junk that was dropped when it was
new. I straightened the door so the latch would operate, but it's
nothing to brag about. I will say that I have only bought one microwave
in the last 30 years, and I paid $2 for it at a thrift store with a bad
interlock switch that was repaired with a used microswitch. The rest
were all picked up as junk & repaired.

Uh, say what?! How'd you get into a personal attack? Why do you
consider me "...pretty dull,...."? Boring, probably, Dense, no.
Especially, not so 'dull' as to expect the $46 microwave oven to last
very long. I simply was sharing my experience, reinforcing someone's
tongue in cheek comment about how it is not necessary to clean the
microwave surfaces because the microwave will fail first! The
poster's joke was like all good humour, based in truth.
Don't know why YOU assume a leftie, member of the Republican National
Committee, personally invited by Bob Dole to join the Republican Inner
Circle. More details witheld because this IS a public forum regarding
home repair and most importantly, this is NOT a political forum.

Again for the denseness you have been displaying. Not dumb, either.
As I said, I didn't expect much from the product, but was surprised
the Chinese didn't have decent plastics. Active circuitry I expected
to fail, not passive housing.
With your last statement, you show your true character. You are
describing yourself when you try to call me a liar. Upon rereading my
last paragraph, perhaps I am lying to myself that this is not a
political forum. Other statements are true.
