My computer arrived on Monday. so I've had a few days to load it up with my backed-up data from the old box, and use it a bit.
Short answer: I like it very much.
Longer version: Early indications are that it is far more capable of doing the processor-intensive tasks image processing demands than my laptop had been.
For astronomy images, it rather effortlessly loads and works on as many as 25 40mb images at a time, something the old laptop was very slow at. All in all (with not a lot of experience), it seems much, much faster.
For "normal" images, I've done much less with it (it's been foggy every day this week, except Wednesday, when I was skiing all day). But it also seems better. Lightroom still is not instant, but it is much, much faster than it was with the old machine. And PS will stitch much more willingly.
It's nice to see it working with 6 or 7gb of my RAM, and the machine is still very happy to do other things. The old machine was brought to its knees in those circumstances. For instance, I'm now performing the first full-system backup, which would mean that I couldn't do anything else with the old machine. I don't even notice that it's doing the backup as I am doing this (but it is, quite fast).
It's really too soon to tell, but preliminary indications are that some combination the extra RAM, the SSD hard drive, the great processor, and the good video card makes this machine much more user-friendly for what I need it to do.
