I have run both Iridium and Global star phones in the BW, neither of which turned my crank...cost, bulk, battery issues, and plain outright coverage issues. Made the switch over to a spot 2 this year and I am not turning back unless I go further north then well that is another story. Simple to operate and program, that my nine year old can cover it. All messages sent on its maiden voyage this summer, so the verdict is still out so to speak. The google earth links are pretty kool too. Now I we have true solitude and peace of mind for the outsiders at the press of a button, or rather buttons. And  the customizing options in the messages spice it up a bit yah know, and it all fits in the front pocket. ;)
