Sony's Reader Wi-Fi offers multi-touch display, is super light

With so many eReaders on the market, can Sony bring the focus back on its own Reader line?

Similar to what's happening with tablets, it's becoming increasingly hard to tell eReaders apart. Sony probably knows this better than most, considering that its own eReaders have fallen by the wayside as the Kindle and Nook have taken over. But can Sony turn the tide?

Enter the Sony Reader Wi-Fi. The latest Reader's "enhanced" multi-touch display works with both finger and stylus input, the latter of which also allows users to both take notes and highlight text.

At 8.9mm thick and 168g in weight, the latest Reader is far lighter than the Nook, Kobo, and Kindle. That's a big deal for a portable device -- assuming, of course, that its build quality isn't sacrificed.

With the latest update, the Sony Reader adds Wi-Fi, allowing users to buy books from Sony's Reader Store or borrow them wirelessly from participating libraries in the U.S. and Canada.

Strangely, the device still offers a series of navigation buttons, few of which seem entirely necessary in light of the eReader's touch screen. Old habits die hard, I guess.

Available in black, red, and white, the Sony Reader Wi-Fi will sell for $149 when it becomes available this October.
