Oh spring, flowers blooming, bees buzzing, the smell of new e-readers in the air. According to The New York Times, the folks over at Barnes & Noble's digital team are putting the finishing touches on a "fifth e-reading device," to be released during the aforementioned season. Not a lot of details on that at the moment -- the bookseller's not spilling the beans. Given last year's release schedule, timing-wise the device would fall closer in line with the company's e-ink line of products, so perhaps the non-tablet Nook line still has a bit of fight left in it, after all.
