Are they worth learning? That depends. I like automating many of my soft synth parameters and I'm finding having the automation in a lane of its own is fantastic.
But it might not suit you, so the only person that can answer that question is you I'm afraid.
I'm using a 15.6" laptop monitor by the way and I don't find it that much of a problem scrolling up and down to the tracks I need to edit. And Multidock is also a godsend as far as I'm concerned.
And I've not even bothered with screen sets yet, which is something else you can use to manage your precious vertical screen real estate.
I think it's just a matter of biting the bullet, grasping the nettle, whatever, and learning all of the new interface. Or stick with what you are used to, and happy with.
