Amazon announced this week that its newest Kindle, the Kindle Paperwhite, will start shipping at the end of ths month. So what does the new and improved Kindle Paperwhite have to offer that the original flavour Kindle and the Kindle DX don’t? (It makes no sense to compare the Kindle Paperwhite to the Kindle Fire, as they are completely different animals – the Fire being a full-fledged tablet, and the Paperwhite being a reader only.)
