Sony announced yesterday that their ebookstore was now available to browse and buy ebooks via any web browser. This is a stellar achievement for Sony, and it comes a mere 6 years after they launched the Reader Store.
Nope, I'm not kidding there. Sony opened the Reader Store when they launched the PRS-500 way back in 2006. You could only access it via Sony's app, which only ran on Windows (and poorly, at that).
In other news, Sony also released an updated version of the Reader app for Android. According to the listing in, the app has a new UI as well as several bug, stability, and performance fixes.
