Travel Technology - FON: Sharing Internet Access w/ Wireless Router

Just saw this free wireless router offer:

http://www.fon.com/gigaom/

Special Offer for La Fonera for free (shipping cost and sales tax included)

This Special Offer is valid until Thursday, February 8th, 2007 and
limited to 2500 units and users of www.GigaOm.com that have received
their Promotional Code and that also register or are already registered
as Foneros. This Offer is limited to one router per user and shipping
address. You will not be eligible for this Offer if you have previously
purchased a subsidised La Fonera at www.fon.com.

I thought this would be nice to have free wifi access while on the road. The free router is "not bad" also. :p Can our expert FTers shed some lights on this offer and whether it's safe to sign up for it?

I am not too tech savvy to know how safe it will be for the whole internet-sharing setup. I don't have a home network but do have ATT/DSL using Speedstream 4100 modem. If I signed up, would it work for me (i.e. w/o hardware issues)? :o

Thanks in advance for your input.
