Re: As for the Amazon Kindle
1) The real eInk ones killing off all competition for people that want to read books.
2) The "fake kindle" Fire tablet, not a kindle at all, but a crippled Android LCD tablet with a Kindle reader app. Overpriced and locked into Amazon store, compared to generic Android. Yes, an Apple iPad is better than the Fire.

3) Dedicated eInk readers
But it's to do with cost (a decent eInk Reader is only good for text and costs x2 to x5 a Tablet), flexibility and the fact everyone has a phone, and handier in bus etc.
