According to Twitter Poll by 50 different Web SaaS companies, All of them had MacBook Pro Keyboard failure in their team and have been working around them.

If you are telling me even a 5% keyboard failure rate within the first 2 year of purchase is an acceptable number that we can simply stop further discussion and say we agree to disagree.

I was referring to the subset of people who have a problem though, not the total number of customers who bought one.

Even a 10% failure rate would be catastrophic and much worse than previous keyboards.
