How do you use your BlackBerry: When do you charge your BlackBerry?

Here's one that was asked of me and I was very curious to know the results as well. Ever since I've owned a BlackBerry I've popped it on my charger overnight. I usually don't eat too much of the battery during the day, but if I do of course I'll charge it when I need to. I know others that like to use a charger whenever they can - be it in the car, at the office or just sitting at home. So our question today is this: When do you charge your BlackBerry? Are you just a night charger? A charge whenever you can? Cast your vote in the poll and leave a comment letting us know!
