why do you need a kindle if you want to switch from sony to apple?
iPad, iPod and iPhone can display epub files just fine - as long as they are drm free.
Download iBooks for free from the app store ... and install on your i-Device.
Now just use iTunes, import your books there - I recommend using calibre, it's a wonderful software to help with your books, but just importing your books from their folder on your HDD works - connect your i-anything and shove your books to the device.
Open iBooks and your epubs are there, ready to go ....
If your epubs are still drm-infested, google apprentice alf, and come back
you see, no need to buy a kindle at all ...
