Most every other ebookstore reached this conclusion in mid 2011, so there is no reason that it should have taken Sony so long to grasp the obvious.
But they did take a long time, so much so that I'm not sure why they even bothered. All today's news told me was that Sony is a ponderous dinosaur which cannot make a decision to save it's life.
Oh, and the app isn't all that impressive either. It's just a less useful version of the stock Bluefire iOS app with the Sony logo thrown on top.
At least with the unbranded app I can buy ebooks from other stores as well as easily download apps from free ebooksites. With the Sony app I'm stuck with an ebookstore which I'm not sure will be around this time next year. Whoop-Te-frigging-do.
