I treat it like my phone, plug it in every night....

I plug it like a laptop. As soon as it's not in use it's plugged.

I use mine constantly and still only need a charge every couple days. I'm still at 89 percent and I've been on it all day.

Everyday for sure.

So far, I've been really impressed by the life of the battery and it puts my iPhone first gen to absolute shame. I realize that the phone has a smaller battery, yes, but now I kind of expect phones to be on par with my iPad for some reason!

Every day, but only because there are sime days that I get close to 15%. It's almost 10 pm here, and I'm at 75%. I'll still charge it because who knows what tomorrow will bring.

I charge whenever I can....

Every other day. I use it often. Going out tomorrow and buying two or three docks. One for the entertainment center (pandora), bedroom, and table next to couch in living room. Hate to have a dead iPad..

I keep my iPad plugged in to the power cube whenever I'm not using it.. That way I always have a full charge when I leave the house with it.

FWIW, Lithium batteries don't need any special treatment to make them last longer. However, you need to do a deep discharge the batteries from time to time, to keep the "remaining charge" indicator properly calibrated.

This site explains things pretty well: -> How to prolong lithium-based batteries

Great article and didn't realize that frequently topping off the battery was better for it. I wonder what Apple will do once the Ipad batteries start giving it up. (Trade-in, refurbs, replacement battery service, etc...)
