My Paperwhite arrived today- two days early, thank you. The screen is very good- no splotches or discoloration. The lighting is very even. I don't have my camera handy so no pictures for now.
Setup went without a hitch. It came with 5.3.3 installed so I downgraded to 5.3.1, installed the jailbreak, jbpatch, and upgraded back to 5.3.3. Everything is working smoothly. I love this Kindle.
Here's a screenshot with the Charis SIL font, modified margins and justification tweak. Off to play!
Edit: I got the special offers version with the intent of unsubscribing eventually. However, I have a case on the way and once I have that, I'll probably never see a screensaver again anyway. So no hurry in getting rid of special offers.
