Is it still a good idea to design a site that will work with an 800x600 size screen? I've seen it loosened it up a bit to 840x600 on a lot of sites, but still. I'd like 900 for this width.
Of course it's best to have as little -content- on the site as is necessary, for instance, google's home page will never have any problems with screen dimensions. But for someone who wants more on their site, would it be unwise to build a site that doesn't look right unless they're screen is wider than 800px? or 840 even?
