Trackballs are Alive and Well

I have a Logitech M570 for my desktop computer. I have another one for my laptop. I got another one for my daughter. Every few years they break and I replace them.

I find that trackballs are superior to mice in many ways and recommend them to plenty of people. But the average user just gets a mouse, IMHO simply because they don't realize there are better options.

Except BUILT IN on Laptops

There are, however, two specific reasons that they are no longer found (and were relatively rarely found in the past) built in to laptops:

• Cost - I don't know the specifics, but a trackball has moving parts. Moving parts cost money. A touchpad has no moving parts - it is a sealed sensor package. In fact, many touchpads are indistinguishable from the rest of the laptop bezel - just some markings printed around it to indicate that it is there. For the same reason that laptop keyboards (and bundled desktop keyboards too!) keep getting thinner - less plastic and other parts = lower cost. Trackballs do cost more as separate items too - typically much more than mice - but there it is a user choice. With a built-in pointing device, the manufacturer has to cover the cost for all users whether they consider it an advantage worth paying for or not. In the competitive commodity world of 15.4" 5 lb. laptops, every penny counts.




• Size - Thin is in! As laptops get thinner and thinner, a few millimeters of extra height for a trackball becomes a problem. If you make the trackball too small then it loses its advantage in usability over other input devices. These are the same laptops where the extra cost would not be as big a factor - but the trackball still loses.

So why aren't trackballs more common? Because of the mouse on desktop computers. On desktop computers, the mouse caught on better than trackballs. Maybe a more "natural" motion, maybe price, maybe competition, maybe simply because Apple made mice popular with the Mac and Microsoft copied them. So when it came to laptops, the manufacturers struggled with coming up with a substitute since a mouse doesn't work in a small fixed space. The little pointer nub was quite popular for a while - and some people still like them, though I never got the hang of it. There were trackballs in some early laptops. But once the technology was perfected for touchpads, they won the race - no moving parts to break (or ball to pop out or clean), conceptually closer to use of a mouse, which had become popular on the desktop and while laptops were (and continue) getting thinner, screen sizes were getting bigger (and therefore the width & depth of the typical laptop was getting bigger rather than smaller, and the base section has to match the screen section), so there was this handy wrist-rest section in front of the keyboard that conveniently fit a touchpad. People got used to it - end of story.

For those people who want to get a separate pointing device, especially for a laptop that will be used in a confined space (as opposed to a desktop where you have plenty of mouse-moving area on the desk), I highly recommend trackballs. There is a learning curve (for those who didn't grow up playing Missile Command), but I find that people look at it funny the first time and when I show them how to use it, most (but not all) manage to learn how to use a trackball quite well within a few minutes.

Dirt is another issue.

In a mouse, the hole where the ball is exposed is pointed down and stuff naturally falls out. On a trackball it naturally falls in. Goop, especially skin oils, gets stuck to the tracker wheels in either case, but general dirt, crumbs and fuzz is a bigger problem on trackballs.

Arcade machines had the advantage that they sort of floated in the case so the area under the ball was open and the crap just fell into the chassis. In the case of desktop trackballs, where the case was wrapped tightly, it was a bigger issue.

A friend who did DTP for a living (remember those days?) had cleaning her trackball down to an art, flipping, opening, shaking and then back together in a single fluid motion.

As other have noted trackballs aren't dead ("disappeared").
But compared to other input methods trackballs are indeed much less popular or widespread as they once were.

Cost, scale, competing products, path dependencies and consumer psychology are the reasons for this development

Trackballs are great. They added a cool, effective, efficient way to move a pointer on screen. So did the mouse. Which is 'better'? That's largely opinion. I have one.

Both devices cost money to buy. The trackball is in use since 1946 the computer mouse is much younger.

The point is: a trackball needs training to use it effectively and efficiently.
But so does a mouse. It also 'needs training' for real first timers (remember intro-screens, handbooks explaining how it works; like 'point', 'click', 'hold' and 'drag'? Later even intro-videos, now still around for trackpad gestures etc). So this is really the cheap mouse being 'good enough' and training a user for the "wrong" kind of device.

The learning curve for a trackball is probably not much steeper, if any, than for a mouse for a novice.

This is much like people reluctant to switch from QWERTZ to Dvorak or Neo keyboard layouts. Fast 4-finger typists are equally reluctant to really learn 10-finger blind typing, as they are initially even slowed by the new method.

Once companies like Apple delivered their computers with a mouse to a public not used to anything else but keyboards or awkward joysticks, this set a path to lower the cost for manufacturing mice and training users to use a mouse. Switching 'back' (to the conceptually older and at least equally efficient device) was from then on only for the really dedicated.

You witness the same process now by each and everyone adding 'touch' to devices that do not benefit from it (TouchBar anyone?). This devolution towards the lowest common denominator is great for perfect neophytes. A two-year-old now handles tablets with ease. That this doesn't foster intelligent development and hampers efficient methods of inputting in the future is a cost we seem to enjoy paying.

These are the general considerations.

But with laptops specifically: yes, then it's now about thinness.

For a trackball to be anywhere near ergonomic, it has to be of a certain size. Which can be shrunk only so far.

Compare these two iterations:

Both from Apple. The first is the pointing device from the Macintosh Portable from 1989. The device was not loved, but very workable, and its size was inconspicuous compared to the rest of this wonderful behemoth.

The second is the 'Mighty Mouse' from 2005. This is a univerally loathed device, and although it was just designed to replace a scrolling wheel and not even work as a real trackball, it didn't do anything well. And it clogged up fast. Needing a cleaning every time I had come across one.

Within the same space a gigantic Portable trackball occupies in two dimensions, you get a depth of a few millimeters in laptops for a trackpad. Even the tiny nipple on the mouse above adds more depth. And that tiny one is not useable, not serviceable, despite in need for service frequently.

That means for laptops who should have an integrated pointing device you look at a very uneven battle: a trackbal needing quite some space and re-training by the user, vs a trackpad that needs very little space and also less re-training for (otherwise) experienced users, and even the feeling of intuitiveness for neophytes.

Gaming

I can't play FPS or flight simulators with a trackball because I cannot intuitively self-center them. The only games they're good for are bowling and Missile Command - because those are played on an arcade cabinet with you standing in front of it.

It's a lot easier to stop a mouse on-target, then it is to stop a trackball - with a finger still on it, or having removed it. And if you freak out, all of a sudden you're looking at the sky.

If I didn't game I'd still be using my trackball.

Fatigue

I had two different trackballs. One was the size of a pool ball, the other was ping-pong sized, placed beside your thumb.

Pool ball: there's no where to rest your palm. And the buttons are your pinky and your thumb. Kinda wack.

Thumb size: well, if you've ever used a gaming controller with thumbsticks for hours on end, I don't need to explain how that begins to suck.

Switching to my middle or ring finger while using a standard mouse, instead of my fatigued index finger, isn't really an option on a 'pool ball' - and it's definitely not an option on an "ergonomically" hand shaped trackball mouse.

Mine is a freewheeling-track-nub

It's Logitech V550 Cordless Laser Mouse. It's the best combination of everything. If you push in the weighted scroll wheel it toggles into a free spin that will last entire threads. It's also a button left to right, thus a nub of sorts. The only downside is the third mouse button is separate.

I'm using a trackball myself right now. I saw about 12 of them on sale at Best Buy last week. Three of my coworkers use them. I"m not sure where you get that they 'went away' but they haven't. I think it's great for desk space, for precision (I love to game with it over a mouse, which I have to pick up and move back all the time) and to reduce hand fatigue.

As the other answer said, trackballs are live and well. I use a track ball on my PC as well as Mac. I found a fantastic brand whose trackball lets it connect with 2 different computers.

I will add that I find trackballs hard to use for games like fornight where you need to move your player fast. For this, I prefer a mouse.

Other than that I will take a trackball over mouse every chance I have. I prefer the trackball because I get less cramping in my hand with extensive use, over most mice.

One disadvantage is that they are hard to use for users that prefer using a mouse at high acceleration and with the wrist resting - of course using it with a fingertip like a mouse wheel is possible, but rather awkward (especially when the trackball is not made very precisely and tends to seize and jam a bit)....
