Buying vaporware

So, there is all this hoopla about unfair banking practices, customers lured into contracts attractive at first, but with unsustainable conditions later on causing people to default, etc., etc. And the vendors are usually blamed for greed, conning, etc.

But, what about our individual responsibility to make informed buying decisions? I can understand if the language is really obscure. But sometimes language is right there starring us in the face and yet, we still go for it.

For example, I just today purchased an item on line and dutifully signed away any vendor's responsibility for the product by agreeing to the following language:

Because each application is unique, XXXXXX makes no warranty as to the merchantability or suitability of any product for a particular use, nor will we be liable for any indirect, incidental or consequential damages that may arise from the use or sale of our product.

If things go wrong, I deserve no sympathy for my unwise buying decision.

How many times did you agree to such conditions or signed a long tightly typed document without reading it?
