Rumors show that Barnes & Noble is gearing up to release an e-book reader aimed directly at the Kindle. It uses an e-ink screen, has wi-fi, runs Android (i can just see all the hacks now), has an expandable sd-card slot, can download books over the air using AT&T’s network, and (here’s the killer feature) it will let you “loan” your ebooks to other Nook readers. That’s the thing that really differentiates it in my mind.Don’t get me wrong – i love my kindle. I use it almost every day and have never had a problem. But … if i had other friends with Kindle’s and could loan books around … that would just make it all that much better. I hope that a firmware update will address this issue in the near future – especially since it looks like there’s now some competition. Bring it on!
