No idea about 98, but on my Dell XP Home machine it works great with XPlay (http://www.mediafour.com/products/xplay/preview.asp). I bought a $30 CompUSA Firewire card and had no problems with it. That is, after I upgraded the iPod firmware to level 1.1 (http://www.apple.com/ipod/download/). Before that I would get "write behind" errors all the time--after the update I just slammed 5 gigs down to the unit at once without a hiccup.

The iPod's way cool--definitely the best user interface I've ever seen on one of these things (or for that matter on just about anything). I think it would be a great idea for someone to make a car head unit that you plugged the iPod into--using the iPod as a data cartridge. Once their capacity gets to 30 or 40 gigs then you'd be golden.
