I've been having a great time with the GPS device which attaches to my = Palm pilot, very helpful when driving in unfamilar areas. My question = is: would it work in flight (in other words, would it be likely it could = pick up satellite signals from inside the passenger cabin) and is it a = "permitted" device? Wouldn't it be great to know exactly what town you = are passing over on a long flight? Best, Bill Heron
