Looking for a new e-reader? Barnes & Noble is trying to get your attention. The bookseller has knocked a solid $20 off the price of its Nook Simple Touch with GlowLight reader, underselling its competitors by the same amount. This is actually the device's second major price reduction-- the first drop, late last year, matched its price to Amazon's Kindle Paperwhite. Although price cuts often lead up to a device refresh, earlier this year Barnes & Noble was rumored to be stepping back from new hardware launches. Either way, we won't scoff at a cheaper Nook, considering how versatile it can be with a little encouragement.
