The reason why you don't see intel laptops is because intel processors are comparatively expensive, And the AMD AX series rocks the socks of everything but the i7.
The A6 3430/Radeon 6520G chip is a middling take in the series- it's not too fancy, but you'll pull 20-30 frames in Org/SW. (yes, my benchmark is WoW.)
I've got an A8/6620G- it's supposedly capable of 3D TV and the like, but I can't be bothered with that kind of thing personally. I've had no complaints so far.
Frankly, the integrated graphics cards they're sticking in the new laptops are surprisingly robust, and if you can settle for not-ultra settings, are excellent for a budget or on-the-go gaming.
The big thing here is the 6 gigs of RAM at a less-than-$500 price point. It's not impossible to find, or even all that rare, but when you're dealing with integrated chips, those extra few gigs start to matter.
The screen resolution is standard for the screen size- which is to say occasionally way too small. I've had some irritation dealing with windows that don't remember what size they were when last opened, and are in fact larger than the screen (League of Legends being the most notorious offender). It's not a really serious issue, but it is distraction.
Now, the big problem- if you're like me, you leave your laptop plugged in most of the time, so it's not a problem at all, but for that guy who was asking about it- You're not going to get the most stellar battery life out of a 6-cell.
Probably two or three hours of intensive gaming, or six (wifi) to eight (wifi off) on minimal settings.
It's pretty standard in that regard, to be honest.
You could do a lot worse than samsung as a company- either their products work really well or not at all, and then they're usually happy to keep sending you more until it sticks.
EDIT: In regards to the keyboard spacing with then tenkey- I've got a nearly identical setup and have found it to be actually very usable. I think the trick is to slim down the key size and put some space in between them.
