Big news from Barnes and Noble — the retail bookstore chain has just announced two new tech additions: an eBooks Store with more than 700,000 book titles and a free eReader download that works with iPhones, BlackBerrys, Macs, and PCs.

Now I can't say I'm going to be reading a novel on my BlackBerry Curve anytime soon, but I'm thrilled they are opening it up to as many platforms as possible.

The best part is that Barnes and Noble has teamed up with Google to offer about half a million books as free downloads from the public domain. And about that rumored new Plastic Logic eReader device, which would compete with Amazon's Kindle? They are still planning on launching it sometime in 2010.
