I have fallen out of love with Raspberry Pi due to the performance. In desktop mode, I have found it too lacking to be any fun. It even struggles to run the web browser. And things like Mathematica, that you get for free which is awesome, are just much too sluggish to be very much fun.
Yes, although it sounds like the Pi 5 will be a significant step up in this regard. To be honest for what I was doing, Pi 4 was easily good enough. It was just a bit more convenient to be able to get media assets etc on to the device directly, implement a simple UI, etc etc.
