i'd have said 1996 with the https://en.wikipedia.org/wiki/Nokia_9000_Communicator https://en.wikipedia.org/wiki/Nokia_9000_Communicator but it was a niche product that probably didn't appear in the u.s. much. as a psion user i lusted after these devices. but price of mobile data put them out of my reach. i used a psion 5 as my main computer till 99 when i wanted to start ripping cds for an mp3 player amongst other things.
