Well, an LCD isn't exactly something you'd wanna be lugging around, considering how easy it is to damage it. However, if you're going to be mobile, why not opt for a cheap 15" LCD? About as much viewable area as most 17" monitors, very light, and the ones by SGI, Dell, Solarism, and some by Samsung and Sony have very fast pixel response rates. Remember, if you get an 18.1" LCD with a native resolution of 1280x1024, you would have to play at that resolution because otherwise, there will be some blur in the image due to the physical limitation of LCD's. Ever consider a laptop? Dell is now shipping notebooks with the mobile Radeon 7500. That's about equal performance to a Geforce 2 GTS. Pair that with a P3-M 1.2 GHz and that's a pretty decent mobile gaming machine. I can't imagine all but the most extreme settings that would be unplayable on that rig. Just don't use anisotropic filtering or FSAA or any of that and you'll be fine.
