Is it illegal? If not, it sounds like a brilliant plan. I'm shocked that people who work with removing coding bugs on a daily basis are so quick to assume that a "bug" in the tax code is Google's fault.
Just like anything in life, there's a level of effort to science/math/engineering. If you begin when you're 3 or when you're 30, you still are going to have to give that level of effort. I think people confuse those who started early as winning some genetic lottery but in fact, they simply got started earlier.
iphone 5 is my first and last iphone. After getting the core text exploit via a text message, I didn't realize just how little of "my" data I actually owned. Attempting to delete a single text message via my computer was impossible unless I was willing to pay some company $70. Apple's innovation since Jobs is non-existent (at least Jobs could steal ideas and package them in a unique way). Google is a huge company that still innovates so they get my money.
... what do you think is handling the key pressing?... It's not just CSS. The only thing this does that's different than iterating over every element is it splits the hiding to the CSS engine.
Steve Ballmer is the perfect example of why a business person should not run a software company. The opinion that "Steve knows how to make money" is a poor indicator of a successful leader. Microsoft has alienated developers leaving only enterprise developers to create boring interfaces for users causing many personal computer users to find something more aesthetically pleasing (OSX/Ubuntu). A company based solely on making money is like a marriage based solely around sex and benefit to social-status. If you're a .NET developer and this offended you; good. Money != happiness
