The 80/20 rule gets interesting when there is competition in the mix. Why should I see an 80% good magician who spent 20% of the time, when I can see the 100% one? Spending 20% of the time thus gets you ~0% of the money. The same actually goes for tech too, but here the answer is often that the 100% product isn't on the market yet, and by the time it is finished the need for it no longer exists.
