If all of your internal pages link back to the root as "/index.html" and all of your external incoming links from other sites are pointing at "www.domain.com/" then you have split your PR.

You are already in trouble in much the same way that www and non-www cause problems.

You should always link back to "/" from within your site. To make things tidy I always redirect (index¦default¦home)\.(html?¦php¦asp¦cfm¦jsp) back to "/" too, with a 301 redirect.

You can change the technology that runs the website at any time without exposing any new URLs to the outside world. Additionally you make it harder for people to know what technology actually runs the site.
