Long hours of scrabble on line on the laptop has left me with a strained thumb.

I recall it happened to me in Africa as well. Woke pretty sore.

My solution was the Kensington ExpertMouse trackball which I switched to eliminate any use of the thumb and index finger giving.

The ability to lock the drag in particular reduces strain.

I used to use trackballs but gave up.....glad I'm back. :clap:

The addition of the scroll ring ....which is incredibly intuitive plus ultra smooth operation.

Software is excellent.

Anyone else with problems/solutions suggestions.

what i noticed recently is that i seem to have acquired a callous on the tip of my middle finger from using the trackpad. my index finger has a bit too... couldn't figure out what it was from at first!

I used to use them a lot in the early 90's but I gave them up, I kept getting fingers pinched between the ball & the housing. Has the design changed much to eliminate this? I also found I couldn't get the kind of responsiveness I could with a mouse (trackpads didn't exist at that point) perhaps it's worth reinvestigating.

I just bought the Apple Trackpad with Bluetooth,
I have it hooked up to the bedroom computer/T.V.

I can now run the Netflix menu's while in bed now.

I love it.

Much improved since the 90s - I gave up as well...this is a whole different beast.

Silky smooth and that scroll ring is simply brilliant

Hmm, sounds like it might be worth reinvestigating...

I have an earlier wireless model ( pre scroll ring) which is getting rather worn!
Now where did you buy that ~ a look at Kensington.com shows no real trackballs anymore.
And saw this

I use the wired ExpertMouse as a I don't like wireless input devices generally.
Cord is nice and long.

Can't you also do drag lock with trackpads? You should switch to the iPad for scrabble ;)

I work in the scrabble breaks and being able to lock via the trackball I can then move things with the track pad.
I do NOT like gestures.....track pads are hard on thumb joints.

Not the first time this has happened

that scroll ring is pure magic BTW

I almost never use my thumb on the trackpad, do it all with tap instead. Drag is tap twice (hold on second tap), not a gesture. But whatever, if the trackball works for you great ... just saying that you don't have to kill your thumb to use the trackpad.

I love my Magic Mouse. :D

Except when using LightRoom, as ScanMan has mentioned previously, maybe a Magic Mouse plus a Magic Trackpad is my ultimate setup....

I took a look at the ExpertMouse trackball (all that I could find... especially videos) and albeit I have used trackball devices before I don't think this product is for me unless... is the scroll ring velocity sensitive? If it isn't this is a non-starter...

AFAIC, velocity sensitivity for scrolling is the best thing since sliced bread.

Very - the controls are superb and the ring is something that should be on every input device,

One of my clients who edits for a living insists on them for his work stations....so figured I try it and see.
I now see why.

But every one is different - I can't stand Apple input devices and others love the....Kensington seems to have a liberal "satisfaction " policy.

This is surely a huge step up from the past.

I do have a trackball, Except it's an old ADB type,
Never worked that well, I think it needs cleaning.

Perhaps someday I'll use a track ball,
But It'd have to be a blue tooth one,
I like to surf while in bed with my big screen tv.

I guess that's why I prefer the track pad,
It's nice and simple to operate in bed.

Samers. At first I thought It had carpel tunnel written all over it but it's proven to be a joy.

The Mighty Mouse on the other hand...

One of them caused me so much frustration I stomped on it. It kept jamming up during a time critical job and just wouldn't clear. Little lint eating monsters.
