Windows in Windows OS and Internet Explorer are not maximized by
default. It requires user intervention before they are maximized. It is
safe to assume the user did this with full awareness. Meaning, they
might just as well not surf with windows maximized.
Full-screen, maximized windows on other OSs are a rarity.
Then still, do you know about the types of toolbars people surf with?
Statusbar? Buttonbar? Favoritesbar? Googlebar?
the Statusbar, and Googlebar, don't take away any width on
my browsers...
Favoritesbar does, but it's sooo easy to turn it off when I
want to have a wider view.
Anyway, my experience is (purely based on my own behaviour
and that of my 'average-internet-user-friends'), that when
having a monitor that doesn't do more than 800x600 or even
1024x768, everybody uses all applications maximised. And no
fav.bar working. Up till last July, I was one of those
people, I didn't even have an option to make it 1024x768
pixels if I wanted to.
Now I choose to have my screen at 1280x1024, and rarely have
my browser full screen. But.. never smaller than 800x600.
I remember someone said it's nicer to look at fixed width
than to flexible. And I agree with that

I think that has to do with two things: the lines to read
are never too long, and , not unimportant, a good designer
can make a nice 'picture' of the whole site, whereas with
flexible design, he has no way of knowing how people will
view it, and what the composition would look like on their
screens.
An exception for me, are those sites that are purely giving
information, that people want to read, regardless of how
ugly it looks, or how difficult it is to read.
Something like information about medication or diseases
springs to mind.
Who cares what that looks like. But homepages, designer's
pages, anything that people want to look good.. I'd say
fixed design isn't all that bad.
