Panaias: I have a laptop for work.
I have a desktop for games.
I wouldn't know what to use this new Pi for.
But I want one :D
For me it serves these purposes:
1. A quiet (= no fans) and low power consumption "PC" that is running 24/7, so I don't have to start it in order to use it. I like doing tasks that would normally take a very long time anyway (even days or longer) for which I don't want to keep a high-power and fan noisy desktop and laptop on 24/7 for a long time. Tasks like, I dunno:
- running gogrepoc.py in order to download my GOG games, and verify their data integrity too. This can take a very long time depending how many games you have and how fast your internets is.
- converting a couple of terabytes of my old video files to some better and more modern format with ffmpeg (this can take a VERY long time if I aim for the best possible quality; even several weeks).
- downloading some super-rare and old movie or game from the ed2k/kad network with AMule, where it seems to come at like 5kB/s speed because there is only one source for the file and he/she seems to be online only 8 hours per day, distributing the file
- keeping some kind of server (ssh, ftp, web, your personal file server that is accessible from everywhere even outside your home) online 24/7. (That gave me an idea: is it powerful enough to run some kind of web server? I guess why not? Going to google for that.) EDIT: Bingo! Of course it can:

and so on and so forth
2. It is connected to my TV so I quite often use it as my "multimedia PC" as well, watching movies etc. with it. I have a Google Chromecast as well for that, but a Raspberry Pi is more versatile for that, like e.g. watching videos offline.
It is quite interesting how I can do pretty much everything on it I would do on my x86 PCs, including my work... EXCEPT playing modern PC games. It has some games of its own and runs quite many emulators too.
I guess I could live without it too, but I had been looking for such low power "PC" for a long time already, even considering if some kind of low power Android tablet could do those tasks. Anyway, RPi4 fits my needs perfectly.
