Why does the 5 GB cap make this useless. I've been using a Cradlepoint CTR-32A for about a year now with a Sprint mobile broadband USB modem.
I've got 3 (count 'em) computers running off of it - 1 desktop and 2 laptops. I telecommute 2 to 3 days per week running a VPN to work (Virtual Desktop). Wife and child using the net to check mail, surf web, play some games (Webkinz, Nickelodeon stuff).
