A writer deck is a small computer designed for writing without distractions. It's usually portable, and often homebuilt.
They can be thought of as an evolution of the 1980s hardware word processor, itself an evolution of the typewriter. Indeed, some writer decks are billed as digital typewriters.
Some people are making one-off writer decks just for themselves. Some very small companies are making them in small numbers, also often 3D printed and open hardware. (The distinction between someone making a small run for their friends and a small company selling devices to the public can often be hazy.) Alas, these often look a tad hipstery, designed more as a fun novelty toy than as something you could actually accomplish serious work on.
A few mass-produced commercial products fit the bill. Japanese stationery company King Jim has been making a whole series of them, Pomera. I've personally managed to get a good amount of writing done on a Pomera DM250, for example.
A related idea is to repurpose an old subnotebook or netbook for the task. A general-purpose PC lets you install your text editor or word processor of choice, rather than requiring you to learn a new one. It helps to avoid a GUI if possible.
Another related concept is the cyberdeck, which is also usually portable and homebuilt, but used for more general-purpose computing.
