Yesterday I read someone that really knew the differences of a 757 and 737 on the inside, it's not exactly the same as I read. I went back to see if I could reread their post and I found this:

Who Took The 717's Boeing Was Offering? — Civil Aviation Forum | Airliners.net

Still not paying to join. But you know, 1 out of every 10 posts on that website can be very informative from people in the know. The other 9? I'd rather sit in the middle seat of a 739 on a transcon then read what they have to say.
