Classic Nook uses e-ink like Kindle. With Kindle you CANNOT checkout your public library books.Recent ebay deal for Nook was $99 for Wifi+3G which is an excellent price in my opinion. Newer Nookcolor uses LCD.
I went to the walmart around 7:00 AM. There were only few people in front of me in the line. At the most only 15 people in the line for the wii. I guess everyone was able to grab one. Manager mentioned that they have plenty in stock.
