This is the second product I've seen that's taking advantage of low-cost mobile hardware, paired w. relevant local content and cheap in-destination calling. Explora comes preloaded w. Taxi Magic (now Curb: http://www.producthunt.com/posts...) as well as a slew of apps to help uncover the city a traveler is visiting.
The other product is called Handy based in Hong Kong and one of my favorite URLs: http://handy.travel/
Love the guys and the problem they solve. Soon, you will see Tourlandish (https://www.tourlandish.com/) pre-loaded on Explora devices as well. Excited with what lies ahead.
