Same here. However, I let it drain down every three months or so. It's over 2 years old, and I get at least 4 hours on the battery.
Got a tip for us?

Of course a battery will degrade over time, however it is not a good idea to fully drain it on a regular basis. Lithium-ion batteries can reach a deep-discharge state when fully depleted, which causes it to have more problems getting back to a 100% again. When your Mac goes to sleep after having stated that the battery has no more juice in it, it still has a certain percentage available to avoid deep-discharge. The worst thing you can do is to put your notebook away in the closet with an empty battery when your going on a vacation.
I'm going to leave it plugged in for at least 2 days and then 3rd day ill unplug it and then use the battery up to 50 percent then keep it plugged in. thats what the faq is basically saying right? or am i getting all of this wrong?
Mine spends much of its life on AC (on my desk). I discharge it perhaps once a month or so.
I've owned it since august, currently 51 cycles and 99% health on the battery
edit:
at the end of the day, look at it this way: if you leave it on AC all the time, why have a battery at all?
yes they wear out. But if it is worn out, just buy a new battery, or use it on AC all the time. Either you use it on AC all the time from new, or you make use of the battery and then use it on AC all the time if you don't replace it when it dies.
either way, i'm sure apple have designed the battery to work well when the laptop is used as a laptop. so, use that battery if you need to...

65 cycles over a year, 92% battery health according to istat pro.
I'll be on a new computer long before it gets down too far.
I can't believe some people are on 9% battery health!

Go to thein top left corner - About this Mac - More Info - System Report - Power Tab (Left Side) - Look for "Health Information" and look for Cycle Count
Wow... I learned something new today! Thanks!
You're fine. Just relax and enjoy using your Mac. If you read the Battery FAQ, that's all you need to know.
is my macbook supposed to say 100 percent cause its been saying 99 and it was plugged in all day?
You didn't read the Battery FAQ, did you? If you had, you'd know. Read the CHARGING section.
Mine has done that since I got it not long ago. I'm glad to know that's normal. Thanks!
Just remembered my batt was replaced by apple after it budged July 2010. So it's not even 2 yrs old :/
