People who want their websites fast eliminate bottlenecks and streamline their client-side load so it works fast.<p>People who want flashy, pretty, animated sites pay for it in terms of bandwidth and performance.<p>Regarding the "computers faster" argument, you see the same trend in traditional desktop software. Microsoft Office used to be fast, but it gets heavier and more bloated with each release, and there are nearly no features I use that can't be found in Office 97.<p>Linux used to be the go-to OS for a lean, fast system. You can't install any recent desktop distribution without it feeling, well, like Windows.<p>Flash websites continue to become more elaborate, so the sites you saw a few years ago perform great, while new Flash sites still chug along.<p>I don't see website bloat as an issue, but web designers and developers do need to realize that not everyone's machine is as fast as theirs.
