From my personal experience, I don't like running lcd's in their non native res. The quality to me is usually not as sharp and I would prefer to stay in one resolution.
It was posts like the one below that scared me away from the wuxga.
THE POST FROM ANOTHER SITE WAS (from someone else obvsiouly)
i have the 6000d and got it for the exact reason you did, web design and etc... let me say i have the sxga model and even the sxga resolution is too small, i have to bump everything down to 1200 res, then its a little blurry but still workable. also the screen does not have a uniform backlight, probably just mine but i doubt it, if you goto best buy you will see almost all the screens are non uniform, except for the sonys for some reason.. Am planning to return it as it is not that comfortable for webdesign because of the very high resolution and bad upscaling, well not that bad but id rather have a lower native resolution laptop.
As for gaming it is superb, the machine was meant for gaming , this thing can even run bf2, low settings but it can muster up the power pretty good. But sadly i did not buy a laptop for gaming, i have a rig with a 24 inch to do that. Im planning on sendin this thing back and getting something more for my needs, im leaning toward sony because as from actually going to the store and looking at laptops, sony has the best screen and most uniform and accurate. Only downside is the price.
Not sure how the 6000d xga quality is, i would rather have that if the native resolution of the xga was as sharp as the sxga. I also have learned a lesson, dont buy laptops online if you care about the screen, dell really needs a store where you can actually look at the computers.
