acs, you're right that it has a finite number of charges, but remember that it is a finite number of FULL charge cycles. This means that if you charge 50 percent one day, and another 50 percentthe second day, that will add up to one full charge cycle.

On the other hand I've heard that if you don't plan on moving your laptop, it's best to just take the battery out and leave it in a fridge or something at approximately 80% charge. I don't know if this applies to cell phones as well, but I would at least refrain from constantly keeping it on the charger. Otherwise you can charge as often as you please, without any ill effects.
