I do see an intriguing possibilities for devices of this ilk in the business context of making broadband connectivity available in situations where it is not currently available, such as events, free-standing locations (e.g., parks, parking lots, and events).

In the IT Datacenter context, it has a potential niche for emergency broadband as part of a contingency plans. It also has potential for providing broadband support in places that presently do not have it (e.g., tables in parking lots). It also affects the economics of broadband connections at trade shows, which often have heavy installation charges.

In a corporate context, even the potential overuse surcharges on the 5 GB/month plan are dwarfed by the costs of lost connectivity.

A somewhat longer discussion of this potential is contained in my blog, Ruminations — An IT Blog under Corporate Tool: Mobile WiFi Hybrids (see http://www.rlgsc.com/blog/ruminations/wifi-as-mob...
