Barnes & Noble announces new touch-enabled Nook for $139

Not to be outdone by Kobo which just unleashed it's latest E Ink reader yesterday the folks at Barnes & Noble are back with the latest update to their line of Nook devices. The "all new" Nook is touch enabled and lasts up to two months on a single charge. The Pearl E Ink screen boasts "80-percent less flashing" during page turns, something that many fans of the devices have resigned themselves to having their eyes assaulted by. And B&N is quite proud of its streamlined interface which it brags has 37 less buttons than the Kindle 3. Around the back is a soft-touch rubber surface that should feel great in the hand while reading, though, we'll have to wait to manhandle one ourselves to be sure.

The new Nook has a redesigned home screen with your current reading list and suggested titles and adds a few features like FastPage Zoom forward, which lets you jump to any page in a title, and (finally) displays the number of pages left to go. Inside is a microSD slot and a WiFi radio, but sadly no 3G. You'll also be able to share quotes, lend books, and update your status on social networks using Nook Friends, which debuted last year with the Nook Color.

You can pre-order online and in stores now and the updated Nook should start shipping to customers June 10. You'll also be able to pick one up at BestBuy, Walmart, Books-A-Million, and Staples for $139 at the same time.

Barnes and Noble BEA Event 2011

Barnes & Noble selling Nooks for $99 on eBay

What do you do just before you decide to upgrade your old device with some new hotness? You sell the old stuff on eBay, right? Well, B&N doesn't seem to have any better ideas than you as it's started offering its classic Nook e-reader for $99 on the online auction site, undercutting its own price by $50. This is the WiFi-only dual-screen unit, as you might surmise, not the Color tablet that's been treading dangerously close to being a fully fledged Android slate. If you're an E Ink loyalist on a budget, this might just be the opportunity you've been waiting for, though don't blame us if Barnes & Noble comes up with a fancier, more lustworthy model in the time it takes for that free delivery to reach your door.

PSA: New Nook Color partitioning only leaves 1GB for music, other sideloaded content

If you're planning to pick up a Nook Color, keep an eye out for a little blue dot on the box -- no, they're not defective, but new models with the dot have been tweaked to make sure Barnes & Noble retains control of most of that (already limited) internal storage. Updated partitioning leaves just 1GB of internal storage for sideloaded content, such as music and movies, with the remaining 4GB reserved for content purchased from the book and app stores. Previous models allowed sideloaded content to utilize all 5GB of available storage, but the change was made "to ensure ample space for a customer's Nook Library and Nook Apps," according to B&N. We're sure you could figure out how to reclaim those extra gigs, but you won't be able to transfer your entire music library out of the box. Luckily, the Nook still has its microSD slot, allowing you to add up to 32GB of storage for music, movies, and whatever other content you need to keep yourself from using your e-reader to actually read.
