> * Writing python programms
Honest question: what is a real world use case for writing PHP or Python programs on a tiny laptop with a 7" display that wouldn't be better served by a 13" laptop. I can't imagine writing code while standing on a train, for example. But more important, I'm having trouble imagining what kind of work situation would require that.
A computer you can take everywhere when you need to squeeze in extra computer-time into any unplanned free moment opportunistically (e.g. Leetcode practice, dissertation crunch), or being on call and only need ssh & chat access 24/7.
I carried a high-DPI 7" tablet with a keyboard case to good effect. It was less of a physical burden than lugging around a 13-incher, and was inconspicuous when outdoors or places I may have felt unsafe carrying a laptop
I guess this is a very personal thing, but I've always found the weight difference between a 7" tablet and a slim 13" laptop to be pretty minimal, and I walk-commute on average 3 miles a day carrying a laptop.

It's probably a lifestyle choice, but if I were to feel unsafe using a laptop in a space, I probably wouldn't be able to focus enough to work, and instead of using a less conspicuous device, I would relocate somewhere that I felt safe. Also if I were on-call I would doubly want to be in a place where I felt I could focus completely on my work. I don't doubt that the market niche for inconspicuous general purpose computing devices exists, but I don't think it's huge.
You may have misunderstood the premise. I don't want to live my day-to-day life with a laptop on me 24/7, but I can tolerate a pocketable computer. Regular life involves activities in places without lockers - like typing up a dissertation chapter on the train to a ball game, or parking on streets that have occasional car break-ins, to have dinner with friends.
The idea is to make spontaneous computing on the go possible; so the device pretty much has to be on you all the time and everywhere, and I don't think a 13" laptop is a reasonable choice for that.
This made me smile, because that used to be my morning commute. I had around an hour on a usually full train, and I could already start writing things that were on my mind. Everybody is a bit different.
Nevertheless, I have since learned to keep a better work-life balance. I also stopped commuting.
