I avoid Adobe Reader as much as I can because it's incredibly bloated (more so at every new version), insists on taking over my operating system (almost impossible to keep it from checking for updates, helpfully "repairing" components and features that I have explicitly disabled), still doesn't autorefresh, and has uglier font rendering, especially in linux. So I don't like javascript solutions at all.

there are presentation styles that do that indeed and it works as long 
as you don't rely on multipass trickery like automatically generated 
tocs and so (some can be intercepted, some not) .. but it's long ago 
that i used them so there might be clever tricks at work there
