> someone longing for having separate devices again: one for music, one for social networks, one for photography, one for email, etc.

It’s is perfectly possible today. Sony still produces Walkmans and there are 100s digital cameras (not to mention analog ones). I don’t think there was ever a time when SM and e-mail had separate devices.

No, indeed, but^W and that would be an interesting use case. What would a dedicated social media device work, and look like? (actually, that may depend a lot on what privacy one can expect out of it)
