For me: - Easier access to books in other languages or out of print - Quick access to a dictionary - Backlight for reading in bed or in the evening - Pocketability - Way cheaper if you read a lot of public domain books (or have a parrot sitting on your shoulder)

That said, I have a jailbroken Kindle, but I am not giving a cent to Amazon. Should it break I'd just get a Kobo.
