Nothing really. I am happy with it. I just thought if I can spend a little more for a much better lens maybe I should.
You're already getting bitten by the "L" glass bug!! The 24-85 has a good reputation and is a nice all-round lens. I used one for a long time and kinda wish I hadn't sold it.

Canon's longer consumer lenses are not that good. They aren't terrible, but long consumer zooms in general tend to have many sacrifices in their designs. It depends on how much you will use it though and what you will use it for. If it will be used rarely and always in good light then you probably can get by. If not then spending a bit more on a better long zoom would be a good idea. I would suggest you look at:
Canon 70-200 F4L
Canon 200mm F2.8L (prime lens -- amazingly sharp)
Sigma 70-200 2.8
If $$$ is not a concern, look at the Canon 70-200 2.8L. There are two versions, one with IS and one without.
