The original monochrome Nook is great for reading outside. I have an iPad and prefer it for indoor ereading but the screen glare made it uncomfortable for outdoor reading. I understand the color Nook might have some glare issues in outdoor use.
I bought a $99 refurbished wifi monochrome Nook and happily use it at the pool and other outdoor settings. I also did the $15 Philadelphia free library subscription (thank you Avista for the lead!!!) and between that and the free Friday books from B&N, always have plenty of reading material stacked up.
I have grown to prefer ereading to conventional books...much more comfortable to hold and easier on the eyes.
