This comes at an awkward time for me, being on the road and perhaps losing internet access for a few days (in a remote village with weak Net access). I might to give this a spin later this month when I interrupt my road trip with a week-and-a-half trip back home, before flying back to California to resume my road trip. Then I'll be once more busy on the road, to be followed by more eye surgery soon after I drive back home, so it might take a few months for things to return to normal for me.
I never really got the hang of HDX for similar reasons. In the summer when you're less busy and have time for site improvements, I'm usually too busy to try them out.
