Personally, I haven't been too happy with my battery life. It seems to run 
down faster than it ought. I haven't timed it yet, but it just "feels" too 
drain-y. Then again, I'm used to my ginormous 9-cell whopper on my MSI 

I'll get some timing data, maybe, but I wonder if I could hack in a 
battery with more mAh worth of capacity....
