I think HumanSymphony's statement still stands. Even for laptops that's on the low-end.
Regardless, that site is tacky. I hate the bevels on the sub-menus; they look like amateurish crap from the mid-nineties.
The law of the land when it comes to web design is not accesibility for everyone, it's accessibility for your target audiences. I know when I design sites, there is a general target computer demographic: 1024x768 display minimum, IE 6+, Gecko engine browsers (Firefox, Mozilla, etc.), Apple Safari, Javascript, Flash 8 player. People using systems below those kinds of specs are usually lacking money or are just kind of weird (like idiots who whine that Vista doesn't run on their pre-2000 hardware)--usually never-to-be-customers. I won't even bother with Netscape 4.x users; they're unworthy of catering to, and clients will end up paying more for the hours or work needed to get the site to work with NS 4.x than they'd ever earn from such users.
For a laser site like that, the target demographic are people with enough money to burn that they can buy a costly laser. Generally this means they've already spent a good amount on a decent computer, with a decent monitor to boot. Folks on laptops with small screens... well... you can scroll, because you're in the minority for viewing this site.
Still, this site could use some work to just make it more usable and attractive in general, and in doing so, probably manage to cater to those small-laptop-screen users at the same time.
Novalasers will be upgrading their site sometime soon. Hopefully it turns out better than this one did.
