I pulled out my iPad3 to compare font rendering and saw that Amazon had upgraded the Kindle for iPad app with Caecilia. Caecilia is the best font for my tastes on either the iPad or the Fire HD. One thing that really pi$$es me off is that they have a screen brightness slider within the Kindle for iPad app but still don't have that on the new Fire HD. Not only that but the Kindle for Android app on my phone has a two-finger swipe feature that dims or brightens the screen. That doesn't work on the Fire HD either! To change brightness on the Fire HD you have to drag down the dark veil to reveal the Menu and select Brightness, estimate how much to change it because the dark veil makes it guess work, close the veil, and repeat if necessary. Fine tuning can take freaking forever! I'm not sure what dumba$$ designed that but he should be fired.
