Not a fair trade, and impossible to enforce. There's plenty of case law saying that a non-compete that prevents a person from making a living in his profession is null and void.

Apple and Google could be argued to be "competitors for talent", but if you work on one product at Apple and move to Google and work on something different, there's no state in the country that would consider that a violation of a non-competition agreement. To my knowledge, non-competes are only successfully enforced over trade secrets and client lists.
