Charlie. We each have a smart phone which is our camera, e-reader, audio player, Internet access, texting device and guide books. Oh yeah, they also make phone calls. We got a Spanish SIM card with unlimited texts, 100 minutes and 1.6 (in Europe 1,6) GB. I have a 5.5″ LG G3 and Wynette has a 4.7 Nexus 4. Wynette also has an actual iPod.
Talk about a single point of failure. My G3 started rebooting by itself a few times in one day, apparently a common problem with them. Luckily it seems to have healed itself for now since I am far away from t-mobile repairs.
Apart from that we are happy with the devices. They are light. I like the 5.5″ screen in the 5.0″ body thanks to thin bezels.
Little things can cause problems. We charge the devices with a Spain-to-US adapter, a USB charger and a USB to micro USB cable. One charger setup was very slow. By swapping parts I narrowed it down to a weak cable. In Logrono we got a new cable and now all is speedy.
