It's saved my bacon a few times at this point. Basically a (large and unwieldy) cell phone I can pull out when my main driver falls dead.
Pro tip: install ride share apps on the tablet in advance, because in a serious UX fail, Uber and Lyft both want you to receive an SMS code to activate accounts. I was lucky that time, that getting my iPhone out of airplane mode at 1% battery wasn't enough to trigger forced shutdown.
Lyft doesn't even have a separate app, but Uber actually offers an iPad-native experience, but is unable to activate you without SMS. Which, along with standard voice calls, is the one thing a data plan associated with a phone number won't let you do except from the primary advice.
Of course regular taxis are also still a thing ;)
When I lost my phone in Madrid, and realized that I have no way to call a taxi, since I was staying in a residential area where you don't see taxis in the streets.
My Spanish was barely sufficient to explain my predicament, and I lucked out because a random convenience store clerk called me a taxi from his phone.
Which reminds me: in case you didn't notice, there are no more payphones. In 2001, I could walk up to one, and use one of them Yellow Books to do anything you could do one the phone.
Today, you need to have a smartphone to do many basic things.
There are still some payphones here too, but most of them have been vandalised, that's true.
Which in typical fashion, I dropped off just under the deadline, so the office was closed.
Oh did I mention that no there aren't regular taxis on this island anymore? I should have mentioned that first.
(Well, that or Pi 400, but I worry how well the Pi 400 would hold up for travel, or about getting a hotel room with no easy HDMI on the TV)
