If you want to stick with "just reading"--books, and maybe some newspapers and magazines (in black and white)--an e-ink reader ($79 to $149) is probably your best bet. They come closest to duplicating the experience of reading a book, and-- while they have some online features--you won't be distracted while reading by a stream of incoming e-mails, tweets, or Facebook messages.

If you want more functionality--and a color screen--you'll need to step up to a tablet. High-end full-size (10-inch screen) tablets like the iPad 2 (the 16GB version is still on the market), the third-generation iPad, or the Samsung Galaxy Tab 10.1 are much more versatile than e-ink readers, and they can replace a laptop for some tasks. But they'll cost you upwards of $400 or more to start.

But there's a growing class of smaller tablets that split the difference between e-ink readers and full-size tablets. The Nook Color blazed the trail in 2010, and has since been joined by the Nook Tablet and the Amazon Kindle Fire. In addition to working as e-readers, these 7-inch color LCD tablets utilize customized versions of the Android operating system to deliver a growing variety of media, productivity, and entertainment apps. Most significantly, these products are priced from $199 to $249--at least half the price of larger (and, admittedly, more full-featured) tablets like the ipad.
