Your Portable Hot Spot: Wi-Fi hot spot in-a-box

Now you can create your own wi-fi hot spot on the road, on the run and on the fly. The NYTimes’ David Pogue explains and reviews the top three models of a device that’s still in search of its own name. The device is referred to as a “portable hot spot” or as a “cellular gateway” or as a “mobile router.” Some people are even using them instead of their DSL or cable modem so that they can take their connectivity with them and share it with others almost anywhere.
