Nitpicking. Fluid is default unless you change it. Fixed layouts belong to fixed media, such as PDFs formatted for a particular paper size. [with them I have no problem, and, incidentally. I have yet to run into a PDF that is not viewable in a window 800 pixels wide.]

In the same way that Excel 2003 having 64k row limit is not a "bug", but it's still unusable if you have a larger dataset. (From what I've seen on the net, newer versions support up to 1M rows; but the fundamental problem - arbitrary limitation - is still there.)
I really wonder how you would have replied had I written that I tried to read it on my phone or a tablet.
I use media-queries. It looks different on iPhone for example
That is not a browser default. That is fluid vs fixed. Check out smashing magazine for some articles on how that works in HTML/CSS if you're curious.
"fix YOUR bug"
Me not wanting to support people with 800px wide browsers is not a bug. It's a decision. Much like major companies no longer want to support IE users.
