As a ham, I wanted the earl for its ham radio and e-ink functionality. After watching the earl fail to materialize and some other products appear like the rfinder android radio, I've actually come to the conclusion that there's less of a point than I originally thought about combining android and a radio. Eventually, an sdr + bluetooth /usb connectivity to your smart device will be "the way".
However, I recently came across another crowdfunded tablet that I think might be of interest to the earl community. It's the Good e-reader.
No gps, but has e-ink, capacitive touch, and wacom stylus. They come in 13.3" (shipping now) and 6.8" (shipping october). The first run of 13" tablets had some issues (rattling pieces) which they have fixed. For me, I'm hoping to get the 6.8" version and use it as a full replacement for various paper notepads. I could also possibly use this for offline mapping, if I connect a bluetooth GPS to it (i have done this with other devices in the past).
