My experience browsing various through Kindle device isn’t great ( laggy) and so is flicking through pages . This is true for versions of Kindle, but you get used to it.
it looks good. I am not sure if its worth the price since the features do not seem to be too different from Kindle Paperwhite ( Wifi) .
