I have yet to buy any books through Apple's iBook store, so I have a few questions about how it works. Thanks in advance for any and all replies.
Q-1: If I buy books through iBooks, are they backed up to the cloud by Apple?
Q-2: Can the iBooks purchased be read by any device, iPhone or iPad, pc or Mac, either on device or via internet connection?
Q-3: Can iBooks be read via iTunes, either online or offline?
Q-4: Are the books available online only, or is the content downloaded onto the device as well?
