That new Alcantra keyboard, that new pen, THOSE are the things I say have changed, and you can simply buy them separately.
the latency improvements and pen sensitivities in the pen can only be had with the new Surface Pro. they said they're trying to add tilt support to the SP4 but that's not a given considering prior history of adding features post-release.
the surface dial only works on the screen of the Surface Pro and not the older machines. I have the Surface Dial and I don't mind using it off the screen.
the Surface Pro also supports more color profiles besides sRGB. That's important for photography.
it's all up to what you want. some people upgrade cars because it goes 0 to 60 half a second faster than before.
