Satellite Email via GPS?

mtm_king asks: "Has anyone had any experience with Magellan GSC 100 Satellite Communicator? It is a GPS that does email. (Their web site pricing and info is out of date.) The GSC costs $850 unit, $130 for case and antenna, another $50 in sign up fees, then it is $30 a month for the service. My parents live full time in Mexico (outside of Todo Santos, cool place) and just have a cell phone which is expensive and flaky ($1.00 a minute+ from the US) . Trying to communicating with them is really frustrating. I am thinking about buying one of these units for them,but it is getting close to some 'serious money' considering I do not know how well it works. I know I could try to get their PC on the internet through the cell phone but considering that they have to stand by a window or go outside to use it, and the cost of an ISP and more minutes on the cell phone...well, I am looking for cheaper/more reliable alternatives than that." Would the GSC really work better in this case than using the cell phone modem?
