Okay, what does this collection of sort-of-household objects represent? What is their connection to the inset cartoon panel at the bottom, and what’s the joke?

I had a clearly incorrect idea to begin with, that these are the functions which have been supplanted by use of a phone, and thus an indication of how severely she is restricted until her phone is operational again. But no; there really can’t be a hammer-and-saw app that actually cuts wood or pounds nails.

And while we’re looking at it, how accurate is Bub’s memory-definition?

POSSIBLE SPOILER.
In the GoComics comments, there is a pretty plausible suggestion for one of our questions: The objects are things that go on working, without needing an update. IMO imperfect but pretty good — as explaining the selection, even if not the joke.
