Microsoft had been doing it since 2000 but never made it cool. Here's one from 2004: https://www.theregister.com/2004/11/03/review_hp_ipaq_6340/ https://www.theregister.com/2004/11/03/review_hp_ipaq_6340/ I had one since 2000 as a daily driver and I loved the thing, but the app library was horrible. The funny thing is, iPhone launched with no support for 3rd party apps. It took damned near a year for the first apps to arrive.
