In fact, there are quite a few places that can do this. In the city where I live, Shanghai, China, the security is very good and the per capita income is quite high. You can just walk into any coffee shop in the city, leave your laptop there, and then leave to do something else, and it won't be lost, I've tried it countless times.
you are taking this too literally. try to see it as proxy for questions like 'will i get my wallet back from uber drive' or 'will my purse be snatched by street scooters'
That's not actually tiling, is it? To me that reads like fullscreen with workspaces.
If one uses a manual tiling window manager like i3 or sway and a large monitor one can divide the screen into separate work areas that each host multiple applications based on their role in one's workflow and use less workspaces.
Scrolling makes a similar but different workflow practical on small screens where flexibility matters.
Most workspaces are a fullscreen browser or some other app to the left, fullscreen editor in the center, tmux on the right.
I still use tiling within a monitor to view email side-by-side with browser, or a document or two side-by-side with code. Rarely feel the need to put 3+ apps in a complicated layout on one screen since I’m usually not gonna be cross-referencing at them all at once.
If I had one monitor I wouldn’t want to be taking up half of it showing the browser all the time when I could instead use that real estate for more vim splits.
Pixel perfect means it looks EXACTLY like the design comp.
It goes completely out of the window if the browser window isn't the exact size of the mockup.
You might charitably say that pixel perfect means that the implementation intersects with the design comp at some specific dimensions but where are the extra rules coming from, then?
It's an archaic term that conflates the artifact produced by an incomplete design process (an artist's rendering of what the web page might look like) with the actual inputs of the development process (values and constraints).
Mobile is completely hamstrung, all of the effort went into creating as much vendor lock-in as possible rather than into creating a useful pocket computer. There's all this cool tech on and adjacent to mobile that you can't actually use in any meaningful way because every aspect of it is someone's money patch and they don't want to work together.
