I love my Kindles. The original Kindle 3 keyboard helped reignite my love for reading. I have the Voyage which is a great piece of hardware, but to me the Paperwhite is the premier eReader. Its price, along with the most important feature to me, the back light, make it my perfect for my needs.
The one feature on the new Oasis that intrigues me is the ability to invert the screen, that is make the background black and the text light. I think that would be nice for reading at night. But at that $349 price tag, I’ll just wait and see if that feature makes it to the Paperwhite in a future iteration.
