I had a buckwheat pillow and loved it when I had one. I used a tempurpedic pillow for many, many years.
Like Dusty I found that I had allergies and needed to wash my pillows so sadly I don't use them anymore.
I am very interested in the Nook. It seems like it is the best features from the Kindle and Sony Ebook reader models that just came out rolled into one and then some with the color screen, Android OS, and wifi. I will probably pick one up for sure.
I agree with Al as I have a K701, K500 and K400 and the P1 drives them without a problem with a lot of volume swing left to play with. I also have a HD650 and HD800 and the P-1 handles them without straining as Voltron mentioned. I do like the way my HF-2s and RS-1s sound from the P-1 as well .
