Ereaders have come a long way.  I tried the 4th Gen Nook with Glowlight, but like the 3rd Gen much better, it has the navigation bottoms, as well as the dark gray casing that make the text stand out.  I also think that the fonts are even better on the 3rd Gen as well.  It was worth the wait to have a great ereader at a great price.  Will be reading a ton of books on this device.  Happy Camper!
