Probably the main reason is for storage. As most people know you can store you stuff in most any container and generally it is persistent, though that could always end up being changed with a patch, so if that were to happen then owning a house would definitely be the only safe place to store extra stuff. Before I bought my house I was storing my stuff at the Companion Building, in a chest there, it never disappeared on me.
Aside from storage, there is no real reason to have a house yet that I've come across. So far I only have the Whiterun house, maybe the houses in other cities do something a little different. I do feel that I should be able to fast travel straight to my house though. Would at least make having the crafting tables in your house a little more useful, since then you could just fast travel straight there and not have to navigate the city at all.
