I'm using the device metrics override in Chrome to test a responsive website for smaller resolutions (320x480 in this case).
My viewport meta tag is not making any effect on the page in this case. The logo will appear tiny, and I it's completely unreadable. More or less, I'd say I'm seeing everything in a .5 scale.
Here's the head of my HTML:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<link rel="stylesheet" href="css/main.css" />
<link rel="stylesheet" href="css/mediaqueries.css" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" / >
<!--[if lte IE 8]>
<style>
.wrapper {min-width: 960px; padding: 0 10px;}
.hovertext {background: #ccc;}
</style>
<![endif]-->
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/modernizr/modernizr-2.0.6-development-only.js"></script>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="js/main.js"></script>
This does work on other people's sites.... I don't know what I'm doing wrong...

Try this in place of your meta tag. Good luck.
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no, target-densityDpi=device-dpi" />
