If we keep the original prices, the Raspberry Pi 3B should still cost 35-40 EUR (same price as the Pi 1B (+) and Pi 2B when new). The Pi 4B has always been a little more expensive. The 1GB RAM model cost around EUR 45 when new, and with more RAM the price naturally went up. Due to the higher price, the Pi 4B does not replace the Pi 3B.
Raspberry Pi 4B 1GB (2019) was €37 at launch, the lowest price in PW is €34.
Raspberry Pi 3B 1GB (2016) was €40 at launch, the lowest price in PW is €30.
Raspberry Pi 2B 1GB (2015) was €37 at launch, the lowest price in PW is €27.
Raspberry Pi B 512MB (2012) cost €45 at launch, the lowest price quoted in PW is €20.
In 10 years we will have 18% inflation and significant changes in currency value relationships.
@himlims_ I believe the power of “mainstream” PIs has increased enough along with standard inflation to explain the slightly higher price. However, we are still facing a huge shortage and huge demand, which means that the prices are so high due to the supply and demand principle that it is no longer very nice…
But the Raspberry Foundation also has newer series for “mainstream” PIs like Raspberry Pi Zero and Pico.
Raspberry Pi Zero (2015) cost €19 at launch, the lowest price in PV is €19.
Raspberry Pi Zero W (2017) cost €35 at launch, the lowest price in PV is €11.
Raspberry Pi Zero 2W (2021) cost €17 at launch, the lowest price in PW is €17.
Raspberry Pi Pico (2021) cost €5 at launch, the lowest price in PV is €4.
I can use the Raspberry Pi Zero 2W for a lot of things I previously used a 3B for… Yes a 3B is more powerful, but overkill for a lot of things/projects. At normal prices so you not only get a card cheaper than the “mainstream” PIs, but also much cheaper. In the future I expect Picos that can replace a Zero 2W for many projects at a quarter of the price and need only very little power…
