Secondary helps with the clarity of the beer.
When I do Lagers or lighter Ales, I always do a secondary. If you're cleaning your stuff properly, there's no more risk, and after the primary has done it's job, there isn't a lot of room for infection with alcohol already present.
I also dry hop in a secondary. It's more work, but if I wanted easy swill I'd just buy it.
Easier to bottle from a secondary because you can get more beer out of it if you aren't worrying about a big yeast cake on the bottom.

I don't use finings in my beer to help clarify it either.
It's really difficult to get that kind of clarity without transferring to secondary.
