Iridium network, monthly plans available - both key features of the DeLorme that have to be stressed.
Recharging vs. swapping in a new battery is a minus, but that's how all devices are going. So pack your heavy USB battery bank on longer trips.
Not sure I like the dependency on smartphones for mapping and other features, though. More points of failure, more electronics to carry and keep dry and charged, although I did carry all that stuff this summer for other reasons, all on top of a sat phone, so really not that big of a deal.
If I ignored my preference for being able to call voice and reach land lines, I'd be all over this device.
