I have found that rotating 90degrees and reducing font to 14pt really shows how nice the screen is ...

Its so amazing to see how much information i can fit on the screen... its almost like reading a whole traditional page in a book.. and with equal clarity.
I find theres so much information that screen dims before i finish page in some pages (2 mins max?).

You can also page through pages with finger/knuckle presses on top and bottom of screen to page next page prev. This is helpful in rotated mode.

The selection of books at http://www.memoware.com/ is great as well.
