Given the task definition, example input & output, solve the new input case.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Output: Negative
Review writer does not like the book because it was boring, therefore it is a negative review.

New input case for you: The description doesn't address the compatabilty issue with your computer. In my case, I purchased two, and had to return them both, since neither was recognized by my computer. Although the seller took them back for full credit, it's still a hassle, and a disappointment that it didn't do what was hoped it would. The rating doesn't necessarly rate the product, since it couldn't be rated because it was not compatable, it's more towards the lack of documentation regarding compatability.
Output:
Negative
