Just so you'll know, resolution has no effect on the rendering of a webpage. A given webpage will look identical on ANY resolution screen, provided you look at it in a browser viewport that has the same width. This suggests (correctly) that the limiting variable is not resolution, but browser viewport width. If you want your page to adapt, then use the browser viewport width to determine how it should adapt, not the resolution. And by the way, I completely agree with Nancy's suggestion and Ken's analysis.
