I hate to jump into this fray with a minor point, but screen size isn't the
issue here. It's window size, and users can resize their browser windows as
small as they like. I certainly don't open mine to full screen width all
the time, and it certainly has been narrower than 512 pixels at times.
HTML should remain browser and platform independent. There, I've said it.
While style sheets may hint, any assumptions whatsoever about the browser
or platform are bound to run into difficulties. I for one am VERY glad that
we have hard-of-sight and blind constituents, as serving their needs will
keep us on track. A strange angle possibly, but valuable. (I *try* to
remember the ALT attributes on my IMG elements.)
