Then there are the requisite software tweaks to improve the NookHD's usability, all of which appear—in the short time we spent with the devices, at least—to actually be useful. The device can store up to six libraries for individual users; this way dad doesn't have to sift through junior's Archie comics to get to his Sports Illustrated. From the lock screen, drag the unlock icon onto whichever library you wish to enter. As for the homescreen itself: there's nothing remarkable here, just close mirror to the Kindle Fire, with recently-opened items up top and pinned items below. B&N, though, has added a nice scrapbooking app, which allows users to pin magazine and catalog pages into files they can refer to later on, and an improved recommendation engine pulls up content across all media—books, magazines, comics, catalogs, movies. All the expected stuff is there, too: a curated app store, syncing with Nook apps across devices, email, and a Web browser.
