I got a Kindle Paperwhite (the one that's integrally back lit) for Christmas & am loving it. Am gutted it didn't exist six years ago when I started breast feeding - it's light enough to be used single handed & can be used in a darkened room (to reduce baby waking).
Been using this week to keep myself occupied whilst comforting a snooty toddler. If you like reading & have a small / baby then I'd recommend it heartily. (It doesn't have to be a Kindle - there's also a backlit Kobo too. Team either with Calibre software & get reading without waking the baby or dropping a large volume on them.)
