I think you misunderstood. I stream... My own services. I don't pay anyone, I don't have ads.
I just don't want another device, it's a waste of time to have to copy a sliver of my collection over and over.
1GB? That is basically not even a full album.
To you point though: its bullshit that devices like this one I am typing on have taken away the SD card. My steam decks have 1tb cards, why can't my other devices?
Oh and I listen to music and watch my movies on my steam deck streaming to them too. That's this thing, no matter where I am, I have my music.
