If someone would compare them rationally, they'd see that a "real" Android tablet that costs around the same would have almost no disadvantage and a lot of advantages compared to Kindle Fire: a lot more apps, higher flexibility for anything, better browsers, app sideloading, and on top of all that, they'd also have all of Amazon's services:books, music and videos. So a $200 Kindle Fire would have almost nothing over a $200 Android tablet.
The only problem is that so far none of the manufacturers did that great all-encompassing marketing for a single tablet that offers you a lot of "benefits" and not a list of specs. Amazon did that, and they saw success. I'd like to see at least Google do that with their upcoming (rumored) Nexus tablet.
Being the first to $200 for a tablet that was seemingly as high-quality (or close enough) to an iPad 2, was a big first mover advantage for Amazon, too. A Google tablet that is $200, or even $150, would help. But it might get the same level of impact only if Google is the first to a "quality" tablet that costs only $99. If Google would do that first and promote the heck out of it and what you can do with it, I think many millions of people would want one.
I doubt they could do it this year, but early next year with the 2nd generation it might be possible. But they better do it before Amazon. Because Amazon will definitely go that direction, since their intention is to only sell a massive amount of such devices, to get users to pay for their content.

This is yet another They Gonna Get You Google! article of the sort that we've seen since the days that Android was a pretty sucky wannabe. It is weird that -- with all the success that Android has seen -- people can keep with the same song list as if nothing as changed.
It's much more likely to be the fact that it is supported by Amazon's ecosystem (which is alluded to as a comparison to Apple) and the fact that it debuted at an unheard of price ($200) for quality tablets, and ended up really pushing the market price of tablets in general down.
