Was this article funded by Apple? It's very biased, as demonstrated by the fact that they cite the 22% of people who don't like the Fire rather than the 88% who clearly do. Even if _every_ one of those 22% gave it one star and _every_ one of the other 88% gave it only 4 stars, it's still a 3.75 rating.
My wife got one a while back and she loves it. Sure, it's not an iPad, but it's also only $199, and it fits in a good-size pocket. It's a great little tablet for the price of two nice dinners. I sill prefer the real e-ink, but for getting all the additional tablet features, I'd say it's a pretty good compromise.
Sure, it could use some improvements, but its the first generation, and it does what its advertised to do. Anyone used to Android should have no problem with it.
