Found the $290 Kindle Oasis too expensive? Amazon has a new, familiar e-reader for you. On Wednesday, the e-commerce giant announced a new, more-affordable Kindle that is pretty much identical to the Kindle Paperwhite, but costs only $80. It comes in white as well as black, and has 512MB storage space (the Kindle Paperwhite sport a 256MB internal storage chip). From an Ars Technica report:In addition to the extra memory, the $80 Kindle will have a slightly thinner, lighter, and more rounded design than its predecessors. It will have a touchscreen display as well, but it won't be the 300 PPI screen that the $120 Kindle Paperwhite has (it will sport a 167 PPI display instead). Some reports also suggest that the new Kindle will come with Bluetooth support so blind readers can hook up a pair of wireless headphones to listen to books, along with a note-sending feature that will let you send yourself messages and highlights, which can be exported as PDFs or spreadsheets.
