I'm new here and even after I've read every possible threats about new macbook model's battery, I'm still confused. How do you guys charge your macbook pro exactly? I mean do you leave it plugged-in most off the time or you guys just run on batteries and only charge it when you need to? When I'm gaming or just doing regular stuff, I don't leave it plugged-in unless the battery is getting low. And I also saw this https://discussions.apple.com/thread/4235082?start=0&tstart=0, I really don't understand what the guy was saying... Thanks.
