Yeah, the Surface Pro will be my primary machine. I'm selling one of my Surface Pro 4 i7/8GB/256GB machines and replacing it with the new Surface Pro with i7/8GB/256GB.
I still technically have the Acer S7, Dell XPS13, and Surface Pro 2 with i5/8GB/512GB. My laptops are pretty much relegated to long haul usage (like long plane trips).
And that's in addition to my desktop machines (AMD Ryzen 1800X with 16 GB, Intel i7-6700K, and AMD FX-8350) though my desktops are strictly for video and audio editing as well as PC gaming (though most of my gaming is on my Xbox One S and soon-to-be Xbox One X).
