If battery life is a concern, then this notebook is pretty decent. However, in gaming mode, that life drops like all other gaming notebooks do. This is a decent overlook on that notebook thta even goes into the battery life in detail:

Yeah, I read that. Thing is, it talks about a 5850 that's with DDR3 and one with DDR5, is there really 2?
"Those who would class themselves as average gamers may be thoroughly pleased with the Radeon HD 5850 DDR3. More demanding players, however, will rather reach straight for notebooks with more potent graphic cards (Radeon HD 5850 GDDR5..."
And in another review they said:
"The Radeon HD 5650 delivers
very good gaming performance at a resolution of 1366 x 768, so that a lot of current games can run with high details and activated extras (such as the AA & AF). The graphics details have to be lowered to medium only when graphics intensive games, such as Bad Company 2 or Crysis, and games with DirectX 11 support, such as, Dirt 2, are run." (It's also bold in the original text, so they seem to emphasise that it's a really good card.)
And I thought the 5850 was better than the 5650. These two reviews makes me think they value the 5650 higher than the 5850. That's what made me confused.
And battery time on gaming is no problem. I won't really game without the power cable. But I want good battery for internet and movies and such.
Still, 11 hour Idle time, that's good, and at least 3 hours DVD time, enough to watch most movies, 5 hours surfing, also pretty good for any semi long trips without power outlet. I'm good with those numbers.
@TESgamerKyle: From the review of the Asus you where looking at I found that the Asus had 2,39h of idle battery, but only 1,38 watching a DVD, which is less than most movies. http://www.notebookcheck.net/Review-Asus-G73JH-ATI-HD-5870-Gaming-Notebook.28191.0.html
