This may be a European thing, I don't know.

This wasn't a phone-dialling device or anything. It was a tiny pocket
computer, but unlike something like an HP 95LX, it was a GUI machine
with a diary, address book, word-processor, spreadsheet and so on.

It wasn't the first "digital diary" of course, but it was the best.
Ultimately a later, ARM version of the OS became the basis of Symbian.

But the fact that your pocket address book could dial the phone for
you -- not by being a keypad or anything, just by picking it up,
looking for Bob and pressing DIAL and then holding it near the phone
-- was impressive for its time.

One of my favourite things to do with its successor model (the Series
5) was pull up an address entry, and when someone pulled out a Palm
Pilot and starting trying to scribble Graffiti into it, to stop them
and transmit the contact to them by IRDA. Most Palm owners had no idea
that their devices spoke infra-red and for them to get a whole contact
instantly by wireless was deeply impressive to them.
