How is the battery life for the new MBP w/ LED screen?

[bowlman23]

I'm looking to get a new SR MBP w/ 15.4" LED Matte screen. Can anyone let me in on how the battery life is approximately? Thanks.

If I have a full battery charge, and only surfing the web / ichat, and put the screen on lowest brightness, I get 4.5 hours. You could probably get more with the airport turned off since that takes some power.

Also, make sure to turn BT off as i'm sure that sucks up some juice too.
