Even though I have heard the battery life is not that long, I have to say I'm extremely happy with the one of this laptop. It averages 2-3 hours, which I believe is great. Of course, this also depends on the programs you are running on the machine. Regarding the sound quality issues, the SRS Premium Sound Software that comes pre-installed pretty much solves the whole problem, which takes out almost all the drawbacks of this laptop. The only reason I'm not rating it 5 stars is the layout of the keyboard, specifically the design of the "F-number keys," as I would prefer to hit F5 or F1 by themselves instead of having to press FN and then F5 or else I would deactivate the touch pad. Other than that, this laptop is, in one word, excellent. Recommended!
