> If I were interested in buying something from your web site, I would be less likely to bounce somewhere else as a result of seeing an uncentered container than I would as a result of being told to upgrade my browser.
Depending on the demographics(what do I lose if I don't support outdated IE and how likely is my customer base to be running arcane IE), the amount of effort required to make sure my site runs on arcane IE; your bouncing off somewhere else might not matter to me. I didn't say putting up a notice saying use a modern browser will ensure customers will comply - I am saying that might be a reasonable compromise.
