For the bookworm who's rarely without a bestseller by her side, consider gifting Amazon's newest Kindle. The third-generation Kindle is one-third of an inch thick and only 8.7 oz. Amazon's latest and greatest can hold up to 3,500 books and last up to one month on a charge (as long as the wireless is turned off). The WiFi-only version is $139 and the 3G Kindle is $189.
