One more gadget with the touch screen capability is in the market. PRS-700 is the third model of the Sony’s ebook reader which has a built-in light and a touch-sensitive display. The device also comes with a stylus, which can be used to highlight text or make handwritten notes. The reader will go on sale at the end of the month for about $400. A single battery charge offers up to 7,500 pages of reading. Sony’s introduction of touch screen capability set it apart from the competing Kindle reader by Amazon.
