I really love the automatic update (works with all files, not just poser files) and I miss the Plant Editor a lot when I'm working in Esprit, especially with the additional Pro plant packs E-on has released in the last few months. Other than that not much, even though open gl works I rarely work on a scene that isn't so complex that it works fast enough with open gl enabled, so I just leave it off. Agiel's list is great too, I forgot about the "rendering larger than the screen size" thing, that's really helpful. And like bonnyclump said, there are more varied render qualities so you're not limited to broadcast or ultra, I almost always use superior now because it's a perfect middle ground without sacrificing the time for ultra.
