Uh, is that kool-aid grape or cherry?
Sony readers are pretty good. But so are Kindles, Nooks, Pocketbooks, and others. Most of them offer useful features that Sony doesn't. And they do it for significantly less.
If the Sony brand floats you boat then, great; enjoy your reader.
But don't try to make out that they are anything special; they are not. They don't offer anything you can't get with other readers at better prices, and often done better. Today there is nothing "premium" about Sony readers. They are middle of the pack at best, which is what you'd expect from a year-old design with two-year-old screen tech. They are no longer leaders or even close followers, and if they don't come up with something new, they'll merely be also rans.
