I haven't read the 13 pages on this topic, but I would like to point out that you can only use this device in your cig lighter from what I understand.
That makes it hard to take it with you when you get your car serviced, over to a friends house, etc. etc. when you may want data somewhere other than in a car. That's where a Sprint card (or Verizon or Alltel) has the advantage.
Not really. You can buy a device from Radio Shack for cheap (I have one) that plugs into Ac and provides a cig lighter type socket for home use. They don't cost much.
