Barnes & Noble has just unveiled a new Nook e-reader, during a special NYC event. The device comes with a $139 price tag and its maker claims that this is the easiest to use e-book reader on the market. Page turning latency doesn’t exist and the battery lasts for up to 2 months, which is double the Kindle’s current performance.

On board of the new Nook you’ll find an E Ink screen, with a 6 inch diagonal and the whole casing measures 5 x 6.5 inches. The product weighs 7.5 ounces, it lacks a QWERTY keyboard and ships on June 10. Pre-orders are already available on Nook.com and the original model now sits at $119, for the WiFi version.

The 3G one costs $169, while supplies last, since we expect a discontinuation of the older Nook. I guess that only an Amazon tablet can take this device down…
