The official advice is: "Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. [...] If you don't plan on using your notebook for more than six months, Apple recommends that you store the battery with a 50% charge."

I wonder if using your laptop plugged in at your desk 90% of the time, but carrying it around to use in meetings the other 10%, is as good as their "ideal use."

  Maximizing your battery's life is not remotely close to a science, but as a rule of thumb, discharge to 50% every couple of days then recharge.

    Well as long as there continue to be long, drawn-out, rambling meetings, we're good to go! Although in that case, a short battery life is a feature: "Oops, I'm at 5%! Be right back while I fetch my charger!"

    It's straightforward to do experiments, control factors affecting experiment, collect data, process is well understood electrochemistry... only thing that might make it "not science" is that it's too well understood so you may claim it's just engineering instead :)

When I'm sitting at home with my laptop plugged in for a long time, I usually just unplug the battery from the computer and set it next to the desk. Is this an ok idea?

The battery is still used even if you leave your laptop plugged in -- it uses the extra juice when the system is under high load. I have used my 45-month-old MBP plugged in 99% of the time, and coconutBattery shows 97% capacity at 38 cycles. Deep cycling only helps calibrate the battery charge indicator, but doing so will lower the battery's capacity simply because you're cycling it.
