I went with the Galaxy Book. Found a screaming deal. It's a spec they don't even list on the normal website, only their business site. i5, 8GB, 256GB, Win 10 Pro. All for less than a Surface Pro with less spec, or the Tab S4.

It's been great, HOWEVER, I'm not sure it was the right choice. It's a great piece of hardware, but I think the Tab would be better for a travel companion.

I did go try the S4 out in store. I like the size and android interface for a tablet much better. That said, is it really that much more useful than my S9+ to justify it? Probably not. It's also of course nowhere near as powerful (WHY only 4GB, and older processor, Samsung?). And the screen is super weird, like jelly looking when you scroll things.
