Can a Windows 10 handle the 4K clips the large Ipad pro handles with 4GB; no it can't.

Actually, it can. Here is a (my) SP4 driving the internal panel as well as two external 4k monitors at 60Hz, each playing a fullscreen 4k sample video.     Not only that, but it isn't even breaking a sweat - the processor is only running at 1/2 max clock speed (1.3-1.8GHz on the i5 with a top clock of 2.9GHz) and is still only using ~20-25% of the CPU cycles while decoding/playing the files. 

iPads are nice, and the UI and app ecosystem is *vastly* superior to w10 as a tablet interface. Still, of the three iPads in my house, the only one I use is an old v1 model in my shop because it does a nice job of playing back Plex content or streaming internet radio, and it's not worth selling or trading in. I gave my v3 to my daughter because I don't really need two devices, and the ability to drive two 4k monitors and run desktop software the SP4 fills both my desktop and tablet needs.
