Yeah I agree the SEO issues. Anything that is dependent on search traffic should not be a single page app, as it will hurt your ranking greatly. Google actually runs JS these days, but you'll still get penalized for slow speed if you load all the content in via JS instead of just serving a flat HTML page to the bot. And that's not even considering Bing and other web bots that almost certainly do not have JS running capability. They will just see an empty page. If you are making a dashboard or web app which is not intended to be crawled by Google, and not really dependent on search traffic though then single page is a great way to go.
