Hah I rushed that answer but yes totally agree. When I'm dev'ing for web, I always monitor perf against a crappy old Android phone. Similarly, Chrome devtools makes it easy to simulate a bad network connection. I try to make sure it's tolerable. Also worth noting that analytics makes it easy to determine what device/OS the majority of your visitors are using. Anyone building an app would be wise to pay close attention to this to guide dev efforts.
