CNET's David Carnoy has a preview:
Here are the highlights: Sony says the "glare-free" E-Ink Pearl V220 touch screen has been enhanced for long-term reading. There are new social features (Facebook and Evernote), a simplified home screen, and an updated default book layout intended to make it easier to organize and find books. Smoother zoom in and out, "paperlike" page turns, and improved continuous page turns are designed to improve the reading experience. There are two built-in English-language and four translation dictionaries. Battery life has been doubled from one month to two with wireless off, and the device's control buttons have been redesigned.
Finally, the matte black T2 model includes a free voucher for the e-book of "Harry Potter and the Sorcerer’s Stone," redeemable from the Pottermore shop online. (That's right, only the black model.)
In other good news, you no longer have to install any software on your computer to access the Reader Store; it's all done through a Web-based interface now that you can access from most browsers. Sony says any book purchased via Web browser will be "waiting in the user’s Reader library, ready to be read." Needless to say, Sony was just a bit behind Amazon and Barnes & Noble in this department (I say that doing my best Bob Uecker impression from "Major League").
As noted, the latest Reader now includes new Facebook and Evernote features. Sony says, "Consumers now have the ability to post a short passage from books purchased from Reader Store to Facebook directly from the device along with the book cover, author, and title." You also get access to content you saved using Evernote's Web Clipper feature, and pages saved with Evernote Clearly are optimized for the Reader’s e-ink display. And finally, favorite passages can also be annotated on the T2 and saved in Evernote for later viewing elsewhere.
Mr Carnoy is very polite in his summation:
In the meanwhile, I can't say the Sony Reader PRS-T2 has any killer new feature to get terribly excited about, but at least Sony's Reader is evolving and improving.
Note that it is six dictionaries in this report: 2 English and 4 translation.
