The picture makes it look like it has a keyboard, a screen, and a hinge to support putting it down and typing on it.

My imagined use of such a device is something like this.

I board the bus and there's, fortunately, a seat. I sit down, but a full-sized laptop wouldn't fit between my lap and the seat in front of me. I pull out the computer and finish up typing my notes about electrostatically-driven hydrogen–boron fusion, perhaps switching back and forth between Emacs and Jupyter as I do some calculations that go slightly beyond the back of the envelope.

Then I switch to an OpenStreetMap viewer to confirm where to transfer to a different bus (though the Pocket Reform evidently doesn't have built-in GPS, I can read a map), and check my address book to make sure I know the address where I'm going. Because the disk is encrypted with a strong passphrase, I know that my address book won't fall into the wrong hands even if the computer gets stolen, unless the thieves have video of me entering the passphrase.

I'm arriving early, so when I get off the bus at the transfer point, I stop at a café, sit down at a table inside (out of reach of motorcycle thieves), buy a cappuccino, and bang out a couple of pages of a story I've been thinking about. Probably a first draft I'll totally rewrite, but I have to get through the first draft before I can write something worth reading. For background information for the story, I refer to the copy of Wikipedia in the computer's local copy, using Kiwix.

Then a cool idea about cellular automata occurs to me, so I try it out in JS using Emacs and Firefox, then commit it to Git. I can't remember how to draw circles on a <canvas> so I consult a locally stored snapshot of MDN using Zeal. (If that had failed, I'd've used a locally stored snapshot of Stack Overflow using Kiwix.)

I pay for my coffee, stick the computer back in my pocket, and continue on to my landlord's house, where I pay him the rent.

Then I take another bus to the university; on the bus I use the computer to review the textbook chapter the professor will be teaching today. The desks in the classroom are too small for a full-sized laptop, but the computer fits on one of them neatly. I use it to compute eigenvalues for some of the matrices the professor writes on the board in order to test a hunch I have about them.

After class, I'm chatting with another student, and they mention they're interested in learning assembly language. I pull out the computer and open up a web server I wrote in assembly a few years ago; it's small enough that I can scroll through the code in Emacs while holding it in one hand, so we don't need to sit down.

On the bus home I use it as a music player, playing through my headphones.

At home I charge it and connect to the Wi-Fi in my house and do an incremental backup of the machine to my home server, which is a Raspberry Pi Zero with a USB disk plugged into it. That way, if the Pocket Reform does get stolen, I can restore the full system state onto a new one.

The next morning I see that my web server has a problem. I suspect that disabling Markdown on comments will solve the problem, but I want to make sure they don't look too broken before I push the config live. So I test the config change in a "staging server" that's really just a QEMU virtual machine running on the Pocket Reform. It turns out that it doesn't fix the problem. Once I figure out what does, and test it in QEMU, I push the config change live. (I'm testing in QEMU instead of Docker because the server is an amd64 box.)

Now I want to go visit a sort of Fab Lab that a friend of mine is setting up in the suburbs. So I consult the bus routes on the computer, stick it in my pocket, and go outside to wait for the bus. Once I'm on the bus, I open up OpenSCAD to put the finishing touches on a mechanical-computing lookup table design I'll try to 3-D print at my destination. It looks wrong, so I run git diff, which shows me that I have a forgotten uncommitted change from six months ago that is fucking it up. git checkout multlut.scad solves the problem, and by the time I get off the bus I have an STL file on my MicroSD card ready for him to slice.

While I'm there, I show him a Xyce simulation of a power supply circuit I've been working on, and he shows me that my circuit is too sensitive to noise in a way I hadn't thought to simulate.

At night I have a date. We end up talking about oral sex technique, and I mention an instructional video I'd seen that showed me some interesting techniques; later at home I show the relevant part of the video.

Throughout all this I never transmitted an IMEI to a cellphone network, and I only ever transmitted a randomized Wi-Fi MAC address, and that only when I was at home. I never sent my data to a data center in the United States, China, or South Korea. I never had to overcome artificial obstacles to installing my own software — or hardware. I was never at risk of not being able to install OpenSCAD because it had been removed from the app store because it hadn't been updated in three years. I never had to deal with any malware, spyware, adware, or antifeatures. None of my files were ever matched against a secret government blacklist of forbidden files. The page numbers I looked at in my textbook were never transmitted to Seattle. I never had to do a CAPTCHA to keep my computations from being aborted. No advertisements interrupted the oral sex video, and because it is stored locally, there's no risk that it will have been deleted from the server because of a DMCA notification.

Still, I think it would be better with a camera (with an obvious hardware power switch which activates a camera app when it's turned on) and GPS.
