Those are fair points, but I don't agree with your general point of view. After all, it doesn't matter much if the product is just slightly lousy or awful. You don't end up using the products so the money is equally wasted in both cases.

Let's suppose 30% of all products are duds (i.e. you wouldn't buy them after playing with them for 10 minutes or reading a few reviews about them). So when you buy a product a launch day you pay a premium for getting your hands on it 2 weeks early. The kindle fire was a $199 device, I think, so you're then paying a $60 premium for having it a week or two early. Whether you want to take on that risk is entirely up to you. I personally wouldn't take on the risk, because I know myself well enough to predict I'll feel disproportionately bad when I waste money on a gadget I don't use. It looks like you're the same way. Most people aren't suited to gambling like this.

So you have to take a look at all the anticipated consequences of buying early. And the sour taste of ending up with a dud is part of that. By blaming Amazon for a lousy product you lose sight of the more important conclusion: that this outcome was completely predictable and avoidable.
