If you buy a Nook, one of the perks B&N bestows upon you is one-hour per day of free Nook reading at their store (and hooked into B&N's wifi). You can read anything at all that is in their inventory. I tried it out today.
I was on my lunch break so couldn't read the full hour, but I read War by Sebastian Junger for about twenty-five minutes. Then bookmarked my spot. Supposedly that bookmark should stay and I can go back any day and pick up where I left off.
It was pretty easy to find the book I wanted to read and took only moments to load it up to my device. I found a comfy chair that wasn't in the coffee shop and got pretty darn immersed in the story...til I noticed the time. It was pretty cool.
It's a good 15min drive for me from the office to Barnes and Noble and nearly a half-hour drive from home, so not terribly useful for me atm. If someone however has a B&N in their backyard this could be quite a boon.
