The only thing I have problems finding something that works is Google maps. As an Android user there are a few different options but Google did make a damn good maps app.
What's so good about the apple ecosystem everyone hounds about? I don't see why you'd want to lock yourself into paying 5x more for every tech product you'd ever want. All of that stuff has an Android equivalent and Bluetooth now. It's not 2011.
This is not true, you can't buy a ticket without identification and you can't get past security unless you go through several other checks. Going into a public area like out on the street is not even similar at all. Airports are not public locations, they are much more similar to the interior walls of a private business than a public location, which doesn't require you to pay to enter and produce varying amounts of identification.
