If I have usual (non Hosting Named Site Collection ready web application) on SharePoint Server 2013 farm, is it possible to add SharePoint apps to such a web application?
EDIT Thank you C. Marius and Per Jakobsen for pointing me out the way. But let me ask the question in a little bit another way.
Imagine an enterprise that has SharePoint 2010 farm deployed. The SharePoint admin of this farm is requested to deploy SharePoint Server 2013 farm.
He makes it (as usual) by creating a web application on port 80 without using host header. Then the new farm gets populated.
And then somebody decides to install some app from SharePoint App Store. From what I uderstand a next web application on port 80 and without using host header should be created for hosting apps.
How our brave SharePoint admin could behaive in such a situation?
