Well, the simple answer is that I like Resolve a lot. And as you say, there’s not much else in Resolve’s tier; obviously Color is no longer an option, and while Speedgrade looks interesting, Resolve’s integration with FCP (and FCPX) fits well into my current workflow.
I am indeed on a tower. Not sure what the iMac solution would be, Intensity Exteme I’m guessing. As for dual monitoring, I’d probably have to switch between DVI and HDMI inputs.
As has been reccommended to me on the Resolve forum, I may just buy a small Plasma TV and be done with it.
