It's ALL about advanced materials lock-up. They spend a gob up front on exclusive rights with Samsung, LG, whoever... to fabricate something exotic by present-day standards and meld it into a magical doo-dad we can't seem to live without.
I got the SpotCommunicator for my birthday this year and I love it. Peace of mind for the wife when I go places that require a day to get in and do not have any other access (especially since I have district rangers on my lists and they can help the wife and others understand where I am and what I'm dealing with).
During a recent call with them I found out that they do not charge for pre-defined messages - only custom type-and-send messages. Which means I can pre-load all of the successes and possible escape route messages into the site, sync the device and not have to use my messaging plan.
I've also started including emergency contacts for others in my group (if I'm going with others) using the group feature. Before we go I send them an email that translates the messages I'm going to send them (41 characters per message only goes so far) and directions for those interested in interpreting the lat / long numbers they get.
I upgraded my OS X Server last night. 1st I had to download and install the base Lion OS ( I was a bit concerned), at this point I had a new desktop OS on my server. 2nd I had to download OS X Lion Server to complete upgrade back to a server. It looks like any lion OS on any computer can become an actual server. The server upgrade is about a 25 meg download and an additional 49 bucks. The services features is much improved. php is now a simple on off switch. I think Apple just turned at least 5 million desktops into servers. Simple upgrade path to the Server.
