[citation][nom]andyviant[/nom]Only way this is useful (and unique) is if it somehow allows you to share a wifi connection you are consuming - somehow doing double duty on the wifi antennae. If this is the case, then one person with a boingo subscription (or whatever other public wifi pay service) can share with friends family. Pretty sure this is not the case though. Boo.[/citation]
Did you really ignore the second paragraph? This is for laptops connecting via 3g to share their connection with local devices via wifi. Although, I am baffled at the notion that you would set up your wifi enabled smartphone to use the laptop for internet access instead of just switching on it's own 3g (unless, perhaps, you are friends with iPhone users in one of the many oversaturated areas).
It can be very helpful for mobile teams (in case anyone here was thinking about actually getting a job), since only the boss needs to having sharing ability (like this laptop, or the Verizon MyFi box) and everyone in the area will get internet access. Well worth it for road warriors.
