Title: Enter button stopped working after 3 months Review: I would not recommend this product to anyone. I type very softly but the "enter" button stopped working after only three months. Several other customers have had problems with other buttons stop working after as little as a week or two (see the Amazon discussion forum on this product). Also the space button is really hard to press. The return policy is very unclear and Microsoft charges you 35 $ only to ask one of their agents a question (keybord costing 39$!). Better buy a different keyboard. Is the review positive or negative?
(A).
Negative

Title: Was Einstein wrong? Review: The author reports on an experiment evincing anomalous behavior of coherent (laser) light. The setup is simple enough to reproduce, however the author's hypotheses run counter to current theories of physics. It is posited that photons are massless, which would require an alternate explanation for the photoelectric effect (it is the momentum of a photon that knocks electrons lose), and that photons upon leaving their source do not share the velocity of the issuing frame, in contravention of the Special Theory of Relativity. Is the review positive or negative?
(A).
Negative

Title: confusing and contrived Review: This is the worst DB design book that I've come across. The first few chapters is supposed to 'guide' you through the db design process, but the example is too lengthy and not to the point. The concepts that is to be explained is illustrated by contrived(using the author's own word) examples. Explanation is confusing. Luckily, I got this from a library and nothing to lose Is the review positive or negative?
(A).
