Here is the back of the NexAira 3G Wireless Router (it connects via a cellular wireless card, and then creates a WiFi hotspot that you can connect multiple computers). Its a pretty impressive device and next to buying more ram to make your computer run smoother, if you are a mobile professional that does a lot of work with groups of people, on a regular basis this could be a very very handy too.

The trick is to figure out when all those situations might be where you need a WiFi router but you do not have access to DSL, Cable or ethernet for more than one person.
