If you don’t have a Kobo, the file conversion is also a lifesaver.
I have one of the old Kindle e-readers, and it doesn’t support epub, for example. It does support pdf, in theory, but the age of the hardware means any decently large/complicated pdf bogs it down something fierce.
Being able to use calibre to convert my books to a format it does support is nice.
Is this anything new at all?
Even back in the day, you had people wanting to live in the recent past, because the past usually gets romanticised.
So people in the 1960s might have a rosy view of the turn of the century, and want to go back to the 1930 days of art deco and balls, or those today, that might want to return what they believe to be glory days of 1960. Even if it isn’t actually realistic to how you might live in the past. The average citizen in 1930 was not attending balls at a swanky music lounge.
Give it a few decades, we might also have people from 2050 pining for the 2020s, believing it to be just like the advertisements, where we all live in the penthouse level of skyscrapers, overlooking a vast cityscape.
