More than your average eReader, the Nook Color from Barnes & Noble runs Android 2.1 and offers apps such as Pandora and Sudoku. Reading titles (in black-and-white and in color) is a pleasure on the beautiful 7-inch display, and social sharing features let you lend books and share quotes on Facebook and Twitter.
If your mother already owns the eReader (or if you're feeling extra generous), consider designing an M-Edge jacket. You can upload an image, add text, or play Picasso and create your own design.
