i just got my nookcolor as a early xmas gift, I read about the LCD screen but since this is my first ereader, I am used to reading a lot on PC or my iphone which I also just got a few months back. I love the NC so far, the graphics are great, and it's nice reading on a bigger screen than my iphone 4.
I did not want to spend the money to buy the iPad with 3G, wifi which is the one I wanted, plus I think the NC is a little more portable it seems. It was little more expensive than the Kindle with 3G, wifi, but I'm not a big amazon fan, and I love B&N. Plus I like that I can take it to the store if need be.
I'm not a techie, so the PDF, etc I haven't a clue, I'll be lucky to figure out the music and video parts!
The only thing I'm disappointed in is that 3G wasn't offered, hopefully this will be in a upgrade?
