Hey guys... I'm not sure that I fully understand the expresscard slot on my new unibody MBP, but I want to... seems like there's a great deal of potential to be had there... what are some of the cards that you'd recommend? What are their uses? Are there cards that will allow for internet access anywhere in the world via satellite (or something to that extent?), say, if I were in the Cambodian jungle for a month or two? Also, what kind of price ranges are we talking for these things?
