It's a pity. I recently added a Nook to my gadget collection and frankly it's not as nice as the Sony. Yes, it has wireless, but I had to turn it off to keep it from sucking down my battery. I could get used to not having the full touch screen, I think, but the touch area at the bottom is not as responsive as the Sony; you have to make quite an exaggerated thumb motion to make the page change.
I am forcing myself to read on it for a couple weeks, to give it a proper chance. And it's certainly acceptable - I still like eReading even with the Nook. But IMHO the current Sony readers are nicer.
