Such was not the case with the Pentium 4, or at least for one small group of people. They opted to take Intel to court because Intel's claims of performance boosts weren't quite factual. Then again, anyone who used the Pentium 4 through its various iterations remembers how dismal it was in the beginning. Was it really worth suing over? Now, years later, a judge has said no. Or, at least, he has said that a lawsuit against Intel for “misrepresenting” the speed of the Pentium 4 line shouldn't go forward, and cannot become a class action suit. The case ended up making it to the Supreme Court – where Intel found itself defending the technical performance of their processors. The case isn't over, but will not be as grandiose as the people attacking Intel had hoped.
With the Internet literally crawling with benchmarks and performance gauges before hardware is even officially released and common knowledge being that companies like Intel and AMD are trying to sell a product to you, a lawsuit of this nature seems utterly ridiculous. I for one side with Intel on this matter.
