Everything is running on Pi. But I have Raspberry Pi 4 with 4GB of ram. Actually I have Raspberry Pi 400, which is basically 4GB variant of Raspberry Pi 4, with slightly overclocked CPU and passive cooling, inside small keyboard, but I only got that because Raspberry Pi 4 was out of stock.
I have all of these programs running on raspberry pi, including Flood (mobile friendly UI for qBittorrent, also supports Deluge), and plex media server. It can’t be easier to watch movies and tv shows that way.
I don’t mind paying ~1300€ for a new phone, if that phone meets my need. I know it’s a little bit too much according to how much would other people spend, but if I can get more stuff done with that phone, I think it’s money well spent.
