Are magazines and newspapers on the nookColor the same as the printed version?

It depends on the provider of the content.  Many contain the new nookColor full page view and then offer and article view. Some of the ones I've tried like USA Today are just lame ePub documents that are very difficult to navigate.  They contain all the stuff for which the publisher has digital rights. Some content is not included like advertisements (yeah, cry me an ocean), crosswords, stock quotes, weather, etc. Like I said, It's going to vary by publisher so try a sample.
