Anyone with standard visual acuity should be able to read 8-pixel-high text on it. Your concern would be limited to that segment of the population who already needs to buy large-print books and newspapers.

Please note that the classic Nokia phone is dead as a doornail as far as popularity is concerned; that might speak against their ease of use compared with touch screen “smart phones”… (take home message might simply be “aim for a touch screen”)
> They sold many millions, probably because they designed a UI that even my mother could be coached into learning (believe me, that’s a feat). Up, down, select, cancel, and a numeric keypad. The size of the text on the screen doesn’t seem to have been a factor.
The keypad is sort of helpful to put in say IP addresses (or passwords with a T9 like numerical hash for words system). I have used old HP on printer interfaces to configure IP networking, not an experience I would recommend to emulate (not that you are doing tis, but please keep the failures of old in mind when designing your system).

That reminds me a bit of https://www.securifi.com/almondplus

Apparently there *is* a WPS function, but it’s buried four layers deep in the UI, behind an “advanced” option^W^W “beware of the leopard” sign - and it’s potentially in a different place on each device, making it hard to give directions remotely.
> But with the wifi SSID and password visible on-screen, we wouldn’t need WPS. That’s something an ordinary router can’t do.
Well, a lot of ISP supplied routers have a sticker on the back giving exactly the information (in addition to the password for the web-gui), your alternative would make it easier to change the password and/or SSID; but while the password could be randomized, I envision user unhappiness with randomized SSIDs… ;)
