It has to be able to make phone calls and text on WhatsApp/Signal too, though.
the screen looks like it may be too small for people who have vision problems - no idea if one can adjust the text size used. But the device does "say" the text, so if the user has decent hearing, they could rely on the audio versus reading the text.
Now if multiple in the same area were using this device, it may get chaotic/confusing, but no moreso than multiple people having loud voice conversations in one place.
