How is the battery life of that Asus though?
haha ... well dude, this thing really is a monster, so if you're that worried about battery life I wouldn't suggest it. I've pushed the battery to empty a few times, but I've never actually timed it. AFAIK it usually lasts about 1.5 hours, but you might get a bit more out of it when you use the power saving profiles. Personally I just keep it plugged in whenever I'm using it (yes, it has quite a huge power brick). It does come with a separate small linux installation that allows you to use the turbo boost button as an ON button which boots into a basic linux that allows for basics like web browsing, music, skype etc. I'm not sure how long the battery will last when you use that mode. But to be fair to Asus, there's not much they can really do about the battery life, from what I've read it already has a huge battery pack compared to other gaming notebooks that would easily power a small notebook for an entire day.
The only thing that sucks about using it as a development machine is the fact that for some reason the cursor keys on the keyboard are a bit smaller than the rest of the keys, and they're also not separated from the rest of the keys so when you're doing something like SQL code for instance where you use the cursors all the time it gets a bit irritating since you have to focus more on pressing the right up/down/left/right key each time.
EDIT: A comment I found on the net: "While surfing the Web with minimum screen brightness, we squeezed one hour and 48 minutes out of the G73’s 8-cell battery pack. "
"Battery Life
Testing the battery life of laptops is a contentious thing – do you test for the absolute best-case by disabling everything and leaving the CPU to idle, or do you set a film to loop and measure that? Both of these tests are unrepresentative of what you’ll use for your laptop for the most – a bit of work and web-browsing while on the sofa. We’ve therefore chosen to test by loading up a website with a bit of light Flash animation, which loads the CPU with a moderate amount of work (about 5 per cent CPU load on this laptop). We’ve left the WiFi on, but let Windows dim the screen to half brightness, and also disabled the screensaver and the ability to turn the screen off. Finally, we entered the advanced battery options to make sure that the laptop won’t go to sleep, ensuring that we used the full life of the battery."
