"Laptops can't play games." This is a truism up there with "bumblebees shouldn't be able to fly," "dogs can't look up" and "robots do not understand this human thing you call love." It's baloney.
Even the cheapest laptop on sale today can play hundreds, if not thousands of games. There's an unimaginable amount of casual, web, and indie gaming to be had out there, and the vast majority of it doesn't require discrete 3D graphics or a dualmegamulticore processor. The same's true of retro gaming, be it turn-of-the-century 3D shooters, the classic Interplay cRPGs, or the PC's revered ancients running in trusty DOS emulator DOSBox (www.dosbox.com). A sub-$600 laptop can play all of these.
