I feel like everyone is focusing on the wrong part of the Invention Assignment Agreement. The problem isn't that employers want to force you to not work on anything else (Apple might). The problem is, if you go home, and work on a work related problem, who owns that work. The obtuse case is I work for your company as the lead engineer making TVs. All the TVs can't display blue. I then go home have an epiphany, and develop a method for making TVs blue. We fix the problem and call it day. Later still, I leave the company and sue you for infringement because I technically came up with the solution outside of work and therefore I own that code. This is the situation most companies are trying to avoid. If you solve this problem without having the company own everything the programmer does in and out of work, then you can have stricter walls between work and home projects.
