Familiar with both. Looking for someone who's had more "hands on" than me. Money is not that critical. I do like the fact that the google book offerings could be acquired "over the air" with Nook, whereas Sony is limited to store offerings. Mainly wanting the product that will last the longest and read the best. BTW, I do own a Kindle 2 I plan on keeping for most newer book purchases. I want this for pdf's and google book open source books. Thanks.
