The Earl is a soon to be released waterproof and ruggedized, solar powerd backcountry tablet with all the features you could want for being outside and active in many sports, activities and hobbies.  It has an impressive sensor array, and also a powerful radio chipset with external antenna capability.  

With such an impressive collection of benefits to expand the use of the SENA products, I'd like to propose you get in touch with them and work on a nice interface for using the Bluetooth headset, the SMH-10 in my case, with the Earl for reporting information via audio and communicating with others over their FRS, GMRS, PMR446 and UHFCB channels for up to 20 mile range.  The Earl's initial release has an energy efficient e-ink screen and runs on the latest Android version.  The SDK will be available any day now, and highly encourage SENA to be the first available for this awesome new tool that countless adventurers will be wanting.  As we know, the 3rd party support can be a huge success factor for both parties.

Happy travels...
