If I go to a long meeting with my Asus, I have to make sure its fully charged, and I either bring the spare battery or my AA battery adapter, and more often than not a spare power cord.
I use it to take notes using a BT keyboard. I also check/send emails using wifi during the meeting. And I use the camera to take pictures of the white boards.
The two hour rule is accurate for the Asus in this scenario. I also usually drop the CPU speed down to low, as I don't need the speed for this. The extended battery is not an option, as then its too big for my pocket.
Playing games kills the battery. If I am waiting for something (doctor, son's activity, etc), the battery will drop 30% in about 15-20 minutes. This is with speed set to standard and screen set to 3rd notch. (2nd notch is way too low for me, and turbo just eats the battery up). When I am out like this, I don't carry the spare battery or cords. I want the ppc to be small, to fit in jeans pocket, as my ipaq 3970 was too large (but the battery lasted well over a day of high use). I really doubt you could get through a whole movie on this thing.
My friends dell 50 has similar dismal battery performance, plus he soft resets a few times a day.
If you take the back cover of the 730 off, you can see lots of wasted space. The stylus slot is too big, the full size back cover takes up quite a bit of space, and the bottom lip of the battery slot could be smaller and a drop in type instead of slide.
I love the screen, all the features, and I use them all fully. Its just the battery kills this thing. I just do more work than it can provide power for.
Maybe I should cut down
