My question is...
Will this affect me negatively in the search engines for any reason? More specifically - Google?
I don't see why it would...but you never know with Google.
It means nothing to your users whether you use static pages, PHP, ASP, etc. etc. etc. The extension adds nothing of value either to the user or to their browser. Drop it.
BTW, this is the standard for Ruby on Rails applications. By default, Rails URLs have no extension for HTML-formatted content.
The browser needs to know the Mime-type, and it gets that from a header.
(The truly-progressive will also make non-www their canonical domain name as well...)
