In the late 90s I was required to slowly replace dumb terminals with PCs. One of the older ladies taking phone orders was most put out by this, understandably. She was lightning fast on that terminal. She'd never used a PC (I hit on the idea of using solitaire to learn to use a mouse, which worked amazingly well), and was never able to get to the same speed with one as she'd done on her dumb terminal. It's hard to beat the performance of dedicated devices.

While I agree that dedicated devices can be more efficient than Windows-style user interfaces, and even more so than browser-based user interfaces, many people don't use those modern interfaces in efficient ways.

I have observed countless times how many people fill in a field, than move their hand to the mouse to move the focus to the next field or button, than move their hand back to the keyboard, instead of just pressing tab to move the focus. It's painful to watch. Knowing just a few keyboard shortcuts makes filling in forms so much faster.

Things are getting worse, unfortunately. Modern user interfaces, especially in web interfaces, are made by people who have no idea about those efficient ways of using them, and are starting to make it more and more difficult to use any other method than keyboard -> mouse -> keyboard -> mouse -> ... . Tab and shift-tab often don't work, or don't work right. You can't expand comboboxes with F4, only the mouse. You can't type dates, but have to painstakingly select all the parts in inefficient pickers. You can't toggle options with the spacebar. You can't commit with enter or cancel with esc.

An inventory management app was one of my first paid software engineering projects. Sometime in early 00s I had to rewrite it for Windows because the ancient DOS codebase had a bunch of issues running on then-modern Windows versions. I sat down with the users and watched how they were using the DOS version, including the common patterns of keyboard navigation, and then meticulously recreated them in the WinForms version.

For example, much of the time would be spend in a search dialog where you had a textbox on top and a grid with items right below. In the TUI version, all navigation was with arrow keys, and pressing down arrow in the textbox would move the focus to the first item on the grid. Similarly, if you used up arrow to scroll through the items in the grid all the way to the top, another press would move the cursor to the textbox. This was not the standard focus behavior for Windows apps, but it was very simple to wire up, and the users were quite happy with the new WinForms version in the end.

I recall reading somewhere that the entire point of solitaire (at least the original implementation that came with windows 3) was to teach users how to click and drag, so I'm not surprised that it was good for teaching your colleague how to use a mouse

In my own little world, I saw this first with mail and news readers. It was fast and simple to read mail and news with pine and tin: The same keystroke patterns, over and over, to peruse and reply to emails and usenet threads.

As the network ebbed and flowed, email too-often became unreadable without a GUI, and what was once a good time of learning things on usenet became browsing web forums instead. It sucked. (It still sucks.)

In the greater world, I saw it happen first at auto parts stores.

One day, the person behind the counter would key in make/model/year/engine and requested part in a blur of familiar keystrokes on a dumb terminal. It was very, very fast for someone who was skilled -- and still pretty quick for those who hadn't yet gotten the rhythm of it.

But then, seemingly the next day: The terminals were replaced by PCs with a web browser and a mouse. Rather than a predictable (repeatable!) series of keystrokes to enter to get things done, it was all tedious pointing, clicking, and scrolling.

It was slow. (And it's still slow today.)

I saw this at an airport. Took the same plane twice, one year apart, in between they had replaced the terminal by a web UI. First trip it took 15 seconds from the hostess (well into her 50s) to find my booking and print my pass. Second trip (on the web UI), it took 4 hostesses to team up for something that felt like 5 good minutes to do the same thing.
