What do "Kindle" and "Nook" mean?

Kindle Fire and Nook Tablet

" Kindle " and " Nook " are the brands of e readers for Amazon and Barnes & Noble, respectively. Both manufacturers are book giants-one is the biggest online store while the other is the largest brick and stone one.


Kindle


By definition given by thefreedictionary, kindle has the following meanings:
- To build or fuel (a fire).
- To set fire to; ignite
- To cause to glow; light up
- To arouse (an emotion, for example).

Pretty good meanings, right?
It is probabily given by the branding agency Cronan according to this article: "How the Kindle Got Its Name".  In the same article, it says: "Kindle means to set alight or start to burn, to arouse or be aroused, to make or become bright."
Nook
However does not sme like having such nice meanings as Kindle: 
- a sheltered and secluded place 
- an interior angle formed by two meeting walls
The nook often refers to a comfortable and secluded place to read or have a conversation with someone inside a room, which might be a good explanation of the e reader brand name "Nook" .What I can think is that Nook sounds like "Look" which is easy to pronounce and memorize. Take a "Nook" (look) at a book. Now Nook is meaningful.
