This year's Amazon Paperwhite is similar to last year's with a brighter light on its 6-inch display. There is still no memory card slot or headphone jack and continues to not support both audiobooks and open source EPUB files. Ads cost $20 to remove. (it does obviously support the two Kindle proprietary formats AZW and AZW3, and with some fiddling, Acrobat, txt, Word, and mobi files.
Based on the pricing and functionality it is clear that Amazon has shifted its focus to the tablet market. Unfortunately, Apple, Google and Samsung all have arguably better tablets for the price.
