I like Wikipedia, so I belive WikiReader is a great gadget for those who wanna read articles from Wikipedia anytime.
WikiReader is a convenient pocket device for reading Wikipedia. It’s integrated three million Wikipedia articles. Let you rapidly find out needed Wikipedia topics. It’s powered by 2 AAA batteries, and its monochrome screen supports touch screen operation. Updates for the WikiReader are provided quarterly and available for free download.
WikiReader is priced at affordable $99 USD. You can buy it at Amazon.
