Saw this on Expedition Portal and thought it was worth a mention here: http://www.meetearl.com/
I don't think it would get much use in the SMB but I think it has a lot of potential once you get to the campsite, as well as backcountry exploring. If it actually does what the features say it can do (besides the topo maps; weather, short wave, long wave, FRS/GMRS/MURS, built in solar charging, etc., etc.) then it is only missing an espresso machine and back massager. And bottle opener.
