The 20 dollar minicomputer has now become the 200 dollar rgb keyboard. Still, I’ve tried and using a raspberry pi as a desktop computer but everything is so impractical. Maybe the pi 5 is better, but I do not believe it’ll ever replace normal desktop computers. Raspberry Pi’s started as a small board which you can even run Linux on, with low power consumption, so toucan run it day round for services like home assistant. In my opinion, it should stay that way.
The 20 dollar minicomputer has not become the 200 dollar rgb keyboard. You can still get a ~20 dollar Raspberry Pi minicomputer that runs Linux and has low power consumption: The Pi Zero 2. They expanded their range of products on the top, both performance and price wise, but boards on the other end of the range are still on offer.
