I decided to go with the Nook, traveled all the way to NYC this morning to get one and I LOVE IT!!!!! The screen in my opinion is miles better than the Sony edition with it's almost white background and bold dark font (you can even change the font styles). No glare whatsoever that I can see and reading is a pure joy even with dimmer light. Getting on the store took a very short amount of time. I like that I can download Free samples although they are very brief.
You can read my impressions in the Nook forum. Although the Sony Daily Edition looks beautiful, it's large, the form factor is super and it's a touch screen, the very dark screen and difficulty in reading in even normal lighting was a deal breaker for me. I do'nt need a book light in a normal lit room for the Nook but the Sony daily edition I could see that I would. That is unacceptable to me.
Anyway, I hope everyone is happy with their Sony readers, that is only my experience, I'm sure others would have their own opinions. Whatever makes you happy, go with that e-reader. Blessings to all. I found the e-reader for me at last.
