So my CyBook Opus has given up the ghost. I'm considering a Kindle this time around (the convenience of Whispernet is seducing me). Before I click the buy button, I'd like to make sure that I can indeed move my current ePub collection over to the Kindle. I'm assuming that I just convert to Mobi in Calibre and transfer over? How does the transfer work - USB? (And yes, all my books are liberated ePub.
)
