If I send a pdf to my kindle over email with sub:“convert”, as simple as that, I’ll be be able to read any pdf in kindle format. It’s honestly the best feature of it and kobo isn’t compatible like that, as far as I know. That’s the major reason I can’t switch to kobo. That being said, stylus is huge plus for a first time e-reader, which kindle is missing. So whatever is more important to you, you decide.
