I agree that Raspberry Pi is not a good general purpose computer, but some of these criticisms are starting to feel like a pile-on with partially incorrect information.

> the latest pi needs considerations of cooling solutions

FYI you can run the Raspberry Pi 5 without a fan or even a heatsink. It will safely throttle itself if it gets too hot.

If you're trying to get maximum performance out of it all the time, you will want a heatsink and fan. If you want to run some Python scripts in a Linux environment or even if you're doing heavy work and waiting longer is not a problem, you don't need extra cooling.

> and a beefy power supply (no more just any old micro usb cable into any old usb port)

This hasn't been true in 10 years.

Powering something off of any old USB port means it would have to fit within the 5V 500mA basic specification, which the Raspberry Pi 3 exceeded long ago.

> It was a "microcontroller" you could program in Python

It was never a microcontroller by any definition of the word.

Raspberry Pi foundation has released microcontrollers that run MicroPython in a very user-friendly format https://www.raspberrypi.com/documentation/microcontrollers/m...

Raspberry Pi uses USB-C and USB-C is more generous with power. Almost everything except computers provides 15W. With USB-C, devices request want they and there is no reason has to work with minimum possible.

The problem with the Pi5 is that they use weird profile, 5A/5V, that requires special charger. Most 5V chargers are 100W and beefy. If they hadn't cheaped out on power circuits, they could have used normal 30W charger. They should come out with new version that fixes that.

Theoretically, devices like the iPhone have lower power consumption than that and loads of performance features like recording 4k 120fps video.

Of course, an iPhone costs much more than a RPi, and has much better economies of scale, so they’re not truly comparable.

I think the poster means people treat the R-Pi like an MCU that runs Python. The Arduino was popular at the time the Pi came out but limited. Once the Pi landed, it quickly filled the gap and the Arduino's popularity diminished to the point where it's now a corporate Pi clone.

In practice most USB wall warts will happily provide 2 amps or even more with no overcurrent protection at all. The 500 mA limitation, at least outside of ports on computers (where you'll maybe get a prompt on Windows and macOS), is theoretical.

What's the point of doing so though? If you're doing this, you're obviously using the wrong device. If all you need is to run some python scripts in a Linux environment, you should use a Pi 3 or Pi 0w2.

Agree with your other points.
