Don't worry about me... I own a company that focuses on information security and enterprise networking and before I had to go completely into management I "dabbled" a bit in technology
. There are a few RFC's with my name on them. I just posted the info on those two routers since I haven't seen any, until now, that work with 3G USB modems. I have three wireless devices on our boat at any point in time... boat laptop, work laptop and an Apple iPod Touch. It will be nice, for me, to be able to power up the 3G connection when I get to the boat, and then use it on any device wherever I'm sitting.
SD - there shouldn't be a difference in reception based upon USB vs. PCMCIA. Most of the units I've seen have the same power characteristics. I guess if the antennas are slightly different (higher gain) one may have an advantage over the other.
