Just as long as you’re not searching for a “gaming laptop”. IMO those do not exist to any degree of satisfaction. They are all a “choose two” among performance, size/weight, battery life, and noise.

Unless you are so mobile that you are never ever at home, and the prosect of only scraping mid graphical settings at best while being permanently anchored to a wall outlet any time you play is worth it to you, I’d suggest taking that money and instead putting it toward a combo of a desktop rig and a cheap netbook. You won’t be gaming on the go, but you’ll have a better experience for the price. And if there’s a more mundane task that the little netbook can’t handle, you can, provided you have an Internet connection, always remote in to the desktop workstation at home and delegate expensive tasks to it.

If all you need though is something that runs well with a dozen browser tabs open, doesn’t struggle playing back high definition video, and can handle playing a less demanding game every now and again, you can definitely find laptops that can do that while still being relatively slim, quiet, and cool. Just temper your expectations on how far you can push it.
