I've had my Paperwhite for one week and am still adjusting to the touch screen. My Kindle Keyboard was killed a couple of months ago but my Kindle Basic is sitting on the nightstand neglected. I can scarcely stand to read a book on it and two weeks ago it was great.
A friend of mine complains about her Paperwhite. Fuzzy letters, shadows. She insists my Paperwhite is much better than hers. I put them side by side and listened to her whine. Then I put the same font on both and the same light intensity. For me they were identical. For my friend, they were totally different and mine was superior. I offered to swap but the offer was rejected.
I think the Paperwhite is the state-of-the-art for e-ink readers. For now, I would not buy an e-reader that wasn't front lit.
