Part of high housing cost is due to the investment mindset and housing speculation. However, another part of high housing cost is that other people did put in the work to raise its value. Want to live in a clean, convenient neighborhood? Someone kept the place clean. Many businesses set up shop in the area to make it convenient to buy things and get things done. Certain passionate chef set up a wonderful restaurant so that you can just come by and enjoy good food. Some group of people, leader, or politician put in the political maneuverings that got certain ordinances passed or raised the bonds or taxes to build the public transportation. So over time as people continue to invest time, effort, labor to improve an area, it should be expected that the area becomes more expensive (and desirable).
A Pi4B 8GB is like $75. Add a power supply, case, heat sink, storage, and you’re at like $150.
Recently I purchased a used Dell USFF PC with a 4-core i5-4590S, 8 GB RAM for $50, shipped, from eBay. I mean it does use more power, but it is also more powerful than a RPi. I know, not an apples to apples comparison. But if you don’t need to do stuff with the GPIO, and your machine is just plugged in to the wall, and is just running apps in containers, then a USFF PC (e.g. STH’s project tiny mini micro machines) may be a much better option than a RPi.
I really don’t understand the RPi4’s price point right now. But glad the Pi Zero W exists, that makes so much more sense and at the right price point.
