There's not really a "should". It all depends on what you have loaded in device memory and that consists of preloaded apps & content, apps that you have loaded, your data (PIM & email) and any media that you have loaded in device memory which should really be on the media card.
I've run for months with far less memory available (currently at 9MB but I've been at 8 or less). You just need to keep an eye on it.
