I've had my MacBook for 1.5 years now, and my battery life is still a little more than 4 hours. I keep my machine plugged in all the time, and completely run it down once a month. On the other hand, my friends who have the same MacBook have terrible battery lives. They use the laptop on batteries all the time.
I'm inclined to believe this guy has no idea what he's talking about.
