Fluid or fixed?

In designing the FotaHouse website I come accross the old issue of fluid or fixed design.
Fluid design is one that allows the content to expand to fill the screen whatever the resolution.
Fixed design is specifying the width of the site.

Each has i's own set of problems. Theoretically I like fluid design but in practice it suits text based sites sites better than it suits a site like Fota where there is a need for many visuals.
Odd as it may seem fluid design can be more limiting than fixed-width design as the template for the pages tends to have to be a very simple one.

Anyone got any examples of well designed fluid sites with a graphically rich design?

Fixed width has problems when it comes to various browsers, resolutions and devices. Not to mention legibility due to line width.

Here's an interesting article on that one though:
