Can I get 5 hours battery Laptop...

"It is MAC" - those were my words when I first saw Vista. Guys, don't take me wrong I am not of those anti Microsoft guys...and for full disclosure we develop everything on Microsoft platforms. But what I miss more than anything in my day to day work isn't anything that Vista can give me. I was using MAC few times for QA purposes, and the most impressive things I found were the stability (no need for restarts, no processes were stuck...) and the...BATTERY. The laptop battery last for 5 hours (no need to replace in a middle of a meeting or more important during a flight).
So if someone has something to copy from our MAC neighbor he should start with the important ones...
