A hotspot in my pocket

I’m at a workshop at a conference center with no WiFi.  The
alleged reason is that we’re “somewhere close to” the National Security
Agency headquarters in Fort Meade, MD. 

The good news is that I’m able to get online via my Treo.  Using a utility called PDANet, I just plug the phone into my laptop, click a button, and I’m online over Sprint’s CDMA network at 96.6kbps. 

These days, I expect a WiFi connection wherever I go.  But the
reality is that hotspots are far from ubiquitous, even in major cities
and high-traffic locations in the US.  The cellular network,
through a powerful device like the Treo, provides an ideal fill-in
mechanism for near-ubiquitous connectivity.
