If the majority of your visitors only ever load one page then only the cold-cache scenario matters, and there's plenty of sites where that's the case. Even if your visitors do load multiple pages, if the cold cache load time is fast enough, does it matter that the subsequent pages aren't even faster?

This obviously doesn't work if you're serving up multiple megabytes of CSS+JS, but I suspect they're an order of magnitude or two short of that.
