What better way to highlight the issues that need to be addressed by wireless
information providers (i.e., Reuters, Instinet), wireless software tools
vendors (e.g., SpiritSoft), and wireless terminal providers (e.g., Compaq)
than by looking at a day in the life of a typical businessperson in the
emerging wireless world? When Mr.or Ms. Wireless gets up in the morning, what
might he or she need from a support environment? Necessities will include a
desk-based computer, access to a server, a notebook, and a PDA (an iPAQ, of
