It's PC with Calibre app + USB cable + Kindle = books transferred (not just drag and drop if you thought this as the old fashioned way).

It's a step between but think of Calibre as your own book "store". It's an ebook management app that can automatically convert almost any ebook format into the one your device needs but at the same time also gives you the option to edit the ebook details and stuff like that. It's honestly great, I'd totally recommend it.
