I'm kind of regretting getting the paperwhite over the Kindle Fire HD. Think its worth the extra $70 for the fire HD?
IMHO, I would much rather get (and I have) a Nexus 7 over a Kindle Fire HD. Price wise, they are the same, but functionality wise, the N7 is much better.
Even though I have a tablet (actually a few) I wanted to Kindle Paperwhite for book reading. I prefer e-ink to LCD displays for long-term reading. I have an older Kindle, but the PW has better resolution, and the built in light is nice too.
So in the end, it comes down to your personal preference and what you intend to do with the device.
