Which service would you use? I currently have no 3G service, except for my new Kindle 3 and that barely counts. For the MBA, one would either have to use a USB device or some sort of a MiFi device. Any suggestions or recommendations? The (relatively) cheap 3G is one of the intial attractions I had to the iPad, but in the end, the iPad didn't do enough of what I needed to do. The MBA is a much different animal. I know that there are many WiFi options out there, as I currently use those with my iPod Touch, but am looking for reasonably price 3G, connect anywhere plans for the MBA, if indeed such animal(s) exist. Thanks!
