Can't wait for someone to actually get this thing so we can see how the Barnes & Noble store looks like. Que has their own e-store that sits between the reader and BN for the purpose of re-formatting the output of the BN store to look great on the Que. I believe the Nook uses a native app to present the BN store. When we first saw the BN store on the DR800SG, it was at their 09/2009 unveiling and it was basically a web browser opened to their BN mobile store. In other words, scrollbars, tiny, and ugly.
Will also be curious if the browser can be made to browse web pages, like wikipedia.
