I complained about my 4 hour battery life and the tech said,"I'm checking the forums."
Me: "take your time."
(5 minutes later...)
tech: "It looks like a lot of people are having the same problem.
Where would you like me to send the replacement?"
Me: "Can I pay a little more and get the extended battery?"
tech: "OK, I'll take the price of the regular battery off the price of the extended battery.
And I'll send it next day shipping."
