Opening and charging up your high-tech gifts will be the first priority Wednesday. Come Thursday or Friday, from 1-5 p.m, you might head to the Central Branch of the Free Library of Philadelphia at 19th and Vine to chat with one of its resident Gadget Gurus on how to use the device, especially if it's a tablet, e-reader or smartphone. Staffers will also load that puppy with e-books, audiobooks and music from the library's extensive digital lending collection. Or stop by afternoons on Dec. 30 and Jan. 2-3, and from 10 a.m.-2 p.m. Dec. 31.
