Yep.
I've always been a sci-fi nerd, and recently having been re-reading some of my faves from Asimov and others. It's always impressive how many "visions of the future" have come to pass, and just as impressive (in a humorous way) how many "misses" there are. Characters from stories written in the 1950's have viewers at home upon which they can watch their favorite "bookfilms". A hit for predicting home video, and a miss for not realizing that film would not be the medium at that point. For that matter, The Jetsons had videoteleconferencing. The only "miss" was that it's an upgrade of the phone, not their PC, although that line gets blurrier all the time, too.
In 1999, PDAs were hot, cell phones were gaining traction, and personal audio players had already been around a while. It wouldn't really have been a stretch to imagine them all being combined in a single device, but the level of detail this guy got is pretty impressive.
