Depends on how it's used. I reckon 2GB will continue to be plenty for a home network router or media player, for example, given that ten-year-old models with half that RAM are still doing those jobs.
Off topic but need to know ..
Anyone have experience with Android on RPi5?
I have 2 RPi4 at home and my Philips tv with Androidtv from 2018 has gone inte sluggish mode after the last couple of updates so I would like to move to an external box to get access to streaming apps and Jellyfin.
I just haven't been able to find a good Android/androidtv for RPi4 that is smooth.
I think it depends on what you need it to do. Historically, Raspberry Pi was one of the few SBCs that could produce a fractional video frame rate, for example; others would have to skip or duplicate frames to approximate it. (I don't know if things have changed in this area lately.) Also, this model has a real PCIe port, which has advantages over USB bridges.
