I was shocked to see "text messaging" and "smartphone" as words introduced in the 80's. I would have thought those were 90's words at least (for "smartphone" i would have guessed the 00's in fact.)
It could send and receive faxes, e-mails and cellular pages through its touch screen display and included many applications such as address book, calendar, appointment scheduler, calculator, world time clock, games, electronic note pad, handwritten annotations and standard and predictive touchscreen keyboards.
It had exactly one third-party app (which cost $3K). :)
It looks like some of them are only the way the word was used in that particular part of speech. For example, orbit is listed as 1946 as a verb - but the word was used for much longer as a noun.
