i've used a kindle keyboard for a few years, and recently upgraded to a kindle paperwhite 2. since they are both using e-ink technology, there is virtually no eye-strain - the reading experience is very close to an actual book.

i'm an avid fan of real books - the smell, the touch, the sensation of a real book is irreplaceable. however, i find myself reading more and more on the kindle because of the convenience it offers - i no longer find myself lugging 4-8 books when i go travelling since i have thousands of books in a single kindle 

the paperwhite screen is fantastic, especially with the lighted screen. tablets and PCs are back-lit, paperwhite is front-lit so you don't feel any eye strain since the light is directed downwards. so happy to be able to read in the dark in comfort.

i bought my kindles from https://forum.lowyat.net/topic/1811881
lowest price i can find in malaysia, and extremely reliable seller.

Bought mine from the same seller too back in January. Very satisfied with his timely service. Maybe he's out of the country?
