The display backlight and keyboard backlight have a huge impact on MBA battery life. I've found I can get nearly 5 hours if I turn off keyboard backlight and keep the display backlight at a reasonable, low level.
I get abaut 4,5 hours when doing light things like surfing web or reading email. It'll be even 6 hours if I switch to better battery life mode and use processor preference pane to disable another cpu.

My current MBA was purchased on Monday, August 18, '08, and when I run it on CoconutBattery 2.6.3 and my iStatsPro I'm seeing similar stats, but neither says 100% healthy. And though I just bought my MBA on Monday, it says it's 3 months old. SN#W8823 = 23 Week 2008.
