I've always been a fan of the fre-flowing web site that look good ion any browser art any size AND let users resize the text.
Persoanlly I absolutley hate site that bunch all the content up in one are and leave huge margins on either side. Try viewing
this and
this with a desktop size above 1024 by 768!
At work they like the fixed width thing (760x480 usually), they think that is only thing that looks "professional" So there you go, two different schools of thought there.
