For the last 2-3 years I've been "this close" to getting a few devices and setting up a repeater node on my home roof and my office roof, and one to play with... I love the idea of bringing an alternative to SMS to my area. But at the end of the day, is anyone actually using it for anything?
Some of the official city supported emergency preparedness groups use it in my city. I would say it is largely a curiosity for me, like ham radio.
Been more fun to take it camping and stuff to play around with with friends.
Want to try and send one up in an RC plane soon.
