So, how do your like your new Paperwhite?
I have considered getting one more than once, but as noted above always decided against it because my iPad Mini works just fine as a reader with the Kindle app. The above discussion and recommendations finally got me to decide to get one after all. My experience so far:
In spite of having 300 dpi, the typeface seems less crisp to me than on my phone, which is also around 300 dpi. 319, I think. Maybe because of the display type. I find that it's really no easier on my eyes than reading my iPad, which allows for larger type with the same number of words per page. Too few words per page becomes awkward. Turning the pages also feels less natural to me. Tap or swipe, and the whole page fades and re-appears, whereas with the iPad, swiping actually moves the page to the side as the next page slides in.
On the positive side, the Paperwhite is half the weight of my iPad Mini, and being smaller is easier to hold. That alone makes it an improvement overall. And being able to read in sunlight will be nice when I go hiking. Sometimes, for a rest day, I like to hike a short distance and sit and read for a while. With the iPad I have to find shade, and it's still hard to read out of doors. We've been having overcast weather here, so I have not yet had an opportunity to test the bright-daylight reading, but plenty of people say it is easy.
I'd still say to anyone on a budget that if you have a tablet, the Paperwhite is probably not worth it unless you read out of doors a lot. But if money is no issue, it's a nice way to read books, and for me, the lightness of it makes it worth the cost.
I do fault Amazon for touting a six-week batter life (based on half an hour a day of reading). Who buys an e-book reader if they only read for half an hour a day? They should just say 21 hours. That's still better than tablets. They have a good product, they don't need to try to make it seem better than it is.
