I have been told that one should not leave their laptop battery plugged into the house power (mains) as that will damage the battery over time. I have followed this advice with all of my laptops and have had very few battery problems. I have a ten year old Gateway using the original battery.
I recall seeing some info on this subject in the Apple database but don't have the time to look for it this week.
So charge it and then unplug it.

Perhaps you refer to one of the articles cited below.
Before I retired, my laptops went to work with me; since then they have been "small desktop machines" -- plugged in almost all the time.
Sometime in the last 3 years, while still on Applecare, Apple replaced the battery in this one (MacbookPro5,1) when I brought it in for an unrelated problem. I had noticed no problems with the old battery, but I wasn't about to complain about a replacement.
Since my next machine will have a much longer on-battery time than any I have had before (because it will have a bigger battery, no hard drive, and no optical drive) I will probably use it on battery much more.

See this for Apple's recommendations. Their current advice is correct for any Macbook made in the past many years. They are not hiding anything.
http://www.apple.com/batteries/notebooks.html
Leaving your laptop plugged in will not damage the battery. Apple's chargers and circuitry are "smart." When the green light goes on, the battery is effectively bypassed. The charger is doing it no harm. There is some wear, but it is minimal. However, if you never allow a battery to discharge you do run the risk, over a long period of time, of weakening it's ability to drain and recharge effectively. You will see that Apple recommends fully discharging once a month if you do leave the laptop on a charger most of the time.
Battery life drains away fairly predictably, like gasoline in a car, based on usage, known as "cycles, each drain and recharge. The specific usage pattern does not dramatically increase or decrease your batteries life in cycles, though it will certainly change it's life in calendar terms. Leaving it on the charge full time will eventually cause problems, but this problem is different than wear and can be mostly fixed by draining once a month. Such a battery is likely to last longer, in calendar terms, than one that is drained and recharged every day.

Useful to note that most Macbook batteries in daily use will warrant replacement within the three year term of Applecare. I suspect if we survey this list, we will discover that most people's batteries became problematic in their third year. I would recommend taking your laptop in prior to the end of Applecare and complaining about it's shorter life. Chances are good your battery power numbers will justify a replacement.
Apple seems to think this will not happen on the latest Macbooks. I am skeptical, but we won't know for another year. ;)

The battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate and to keep the battery operating at maximum efficiency. You should perform this procedure when you first use your computer and then every few months after that. If you normally leave your Apple portable computer connected to AC power and very rarely use it on battery power you may want to perform this process once a month. The website www.apple.com/batteries has more helpful information regarding batteries and offers an iCal calendar to remind you to calibrate your battery.

It's a counter in an Apple Store well well-trained people will answer your questions and examine your Apple Products and fix them or arrange for them to be fixed. Sounds like you don't live near an Apple Store.

Yes, one or two years ago. Today I tried again (Opera 11.51), and it crashed after one minute of use. See also the comments here:

Given how helpful they usually are, I was surprised at their response to my question for tech support on this issue. Basically, they stated they're responsible for hosting the mail and making certain it gets from sender to recipient, but not for OS or client software questions.
Seems to me that since I'm using only the Apple-published apps for Apple ecosystem users, they'd be more curious about problems that affect usability (especially on the iPad). They did direct me to their sonic.net user forums for possible help, but when I posted a text-based description of my problem, the only response I've gotten was "upload some screenshots.
Guess I will try Apple online support.
