Ha. I just bought two ESP32-based ones: with a 5" & a 7" TFT display cuz I wanted to try both. My application was an HMI (using LGVL) for a device I'm building to order, but I've since decided that I don't need touch input and thus can use a much smaller display. The devices however, are cheap and really nice for the $30 price tag. Having such capable, easy to use hardware at such a low price point opens up markets that couldn't feasibly be served before. There are a lot of people who need one-offs or very small quantities of devices that can't withstand a 5- or 6-figure development cost. When that cost drops to low four-figures because you can use the Arduino ecosystem, then the cash flows.
