I only just purchased a Paperwhite from Amazon today and I'm very excited to see how it goes.
I didn't particularly mind any of the screens posted in this thread, but we'll see. It's different when the device is in your hands and you're trying to read something.
I actually splashed out for the 3G version this time for ease of synchronisation between that and my Galaxy Note. I was even obscene enough to pay the extra price for priority shipping. Next I'll be ordering caviar!
