These days, more and more people are trading regular books for e-book readers, like the Nook from Barnes and Noble. Sales of e-book readers have almost doubled in the last year alone.
Consumer Report tested more than a dozen e-book readers, including the best-selling Kindle. Testers have also begun evaluating the new Kobo E-Book Reader from Borders.
A key test - how easy the screen is to read. "We're looking to see how clear and crisp the type is in different conditions," Rich Fisco said.
In one assessment, testers use lights to simulate outdoor sun. Readers with backlit screens have problems with glare. Those that don't have a backlight are much more readable in bright light.
Another test sizes up how quickly the pages turn, which can make a big difference. In this side-by-side comparison, the e-book reader on the right takes twice as long to turn a page.
Consumer Reports says there are three e-book readers worth considering - the Nook Simple Touch Reader, the Kindle Wi-Fi, and the Kobo E-Reader Touch Edition. They all cost around $140.
If color is a priority, Consumer Reports says the $250 Nook Color is your best choice. It offers rich color - great for people who read lots of magazines.
Consumer Reports says if you want a black-and-white e-book reader, you can save some money by getting Amazon's Kindle Wi-Fi with special offers. It displays ads, and costs $115, a $25 savings. You'll also get special offers on lots of stuff, including discounts from amazon.com.
