I have a Falcon Northwest Fragbook TLX1. The company currently is currently pushing the new TLX2, making mine obsolete. I've had this computer for a little over a year and half now, and despite it's age, it still runs Fallout 3 with only a few hiccups, although for silky smooth game play I have it set to a midpoint between low and medium.
If you're looking for a good gaming laptop, and you have the money, I tentatively recommend Falcon. I say tentatively because I've had some persistent, annoying, but not serious technical problems with it. Almost all of them are due to oversensitivity issues in the computers external buttons. The optical drive pops out at the slightest provocation or pressure on it, which would not be a problem except that the optical drive is rather fragile and I've had to repair it twice. It is also difficult to get to turn off in any real capacity. The pressure sensor on the computer's on button is waaay oversensitive, and will cause the computer to turn on even if just gently prodded and picked up. The fine people at Falcon fixed the problem once, only to have it pop up again. It also has a weird problem were if the computer's Li-on battery burns out, the computer will freak out and not turn on again until it gets a fresh battery, regardless of whether or not it has a charger plugged in. Furthermore, the computer gets very little battery life because it's equipment is being so demanding.
That being said though, my Falcon laptop is the best I have ever had. Despite being a year and a half old (and somewhat outdated), and despite being the smallest desktop replacement the company sells, apart from niggling technical errors, it has managed to keep up with most of my friends desktops. While for the most part you'll be playing games on medium, for an outdated gaming laptop with great portability, that's pretty impressive. Also, despite the niggling technical difficulties, I've had this computor for a year and half without any serious internal hardware issues (that weren't caused by me being careless.) It works well with Vista (the only real BSODs I have had were due to heating issues. I had some other miscellaneous ones, but updating my BIOS and video drivers solved that). It has a 1680 by 1050 native resolution, and a very pretty screen. The keyboard is great too, complete with a full number keypad.
Before I forget:
180GB HDD
nVidia 8800GTM graphics card
4GB DDR2 RAM
2.4Ghz Pentium dual core
Absurdly good heatsinking
Like I said, it's a gaming laptop that's actually feasibly portable, and damn sexy to boot. The new one just came out, and is pretty sweet methinks. Only issue is that it costs absurd amounts of dough, but if you're actually in the market for a gaming laptop, you probably have that money to begin with.
