My old iBook G4 (going back a few years now) got up to 1,500 or so charge cycles before it stopped keeping a charge

The problem with batteries is heat. You can keep Lithium Ion/Lithium Polymer batteries on a float charge by keeping your laptop plugged in indefinately as most laptops have very good charging regimes. The problems occur when they heat up and that's what will eventually kill them.
As long as they run cool then whether the charger is plugged in or not will not have too much detrimental effect. I sit my laptop on a glass breadboard to ensure adequate air flow under the base.
If I am doing anything heavy like video manipulation, I remove the battery and just run on the power pack on a UPS as the heat generated can be conducted to the battery pack.
If you are not going to use it for a bit, store the battery pack in the fridge. (not the freezer)
