Barnes & Noble on Friday released version 1.3 of the software for its Nook e-reader, which includes a Web browser, faster page turning, and several games. The Android-based Nook now also lets users read books for free in Barnes & Noble retail stores, and fixes a few bugs. Already boasting some capabilities not available in its rival Kindle e-reader, Barnes & Noble’s Nook now goes even further to widen the gap. Nook not only offers double the book selection — one million versus Amazon’s 500,000 — but it also supports the open EPUB format, and even lets you borrow electronic books from public libraries and friends. Nook also allows access via open Wi-Fi points, while the Kindle only can use its own 3G network. A Micro SD memory expansion slot rounds out the Nook’s advantages. – From PC Mag
