Just wish to share.
If you have a rooted Nook and you wish to save a webpage for a quick read without converting it to epub, you are now able to save the website direct from your browser (on PC) to your Nook drive (mine is F and G).
The web file will be listed in My Books. When you choose to read it, Nookbrowser will be automatially used to display it. Pressing back button in Nookbrowser will return you to My Books again.
So basically your Nook is now supporting another format, html!
The good news for me is that if I save the web with Thai filename (with UTF-8 encoding option before saving), Nook will display it in Thai book title too!.
