Its obviously different from a reg laptop battery right? Because obviously with tablets, people will be taking it around more running it off the battery as they would with a laptop. A laptop battery usually is about 300-400 discharge cycles before it starts to show its age and battery life declines. How about ipad/ipad 2? Because like many already ill probably be running the ipad 2 off the battery all the time unless im at home in one spot. How I see it is, people use their ipad like they do their cell phone. Use on battery during the day, charge at night. But I could be wrong.
