My coworker Brent has a NEC MobilePro 900 that he uses on a regular basis. It runs Windows CE and connects to WiFi with a compact flash card. (He could plug the CF card in the front slot, but prefers to use a PCMCIA adapter to put it in the side.)
A few weeks ago he brought it to a tech conference in Green Bay. During the presentations he used it to VPN into his home computer, stream music, and do a host of other things.
The Y2K Family Survival Guide is a recent acquisition for him too. The book is a riot to read ten years after the fact. It even promotes teaching your children about the Bible in light of a Y2K disaster.
