Personally I would never use a notebook or laptop for serious GIS Work. Unless you have a docking station. I utilize 2 x 27" monitors and a 19" on the side.
Spending the extra money on a touch screen is a waste of money in GIS
I don't know how well Pro will interact with Windows 10. We use Windows 7 because the bugs have been worked out and it is stable. My supervisor recently got a new computer with Windows 10 and I have not heard him cussing.
The x360 has sufficient power to run Pro and 8 GB is good for most applications unless you intend on doing 3D.
However, the MX150 GPU is a very low end graphics card and you may experience long refresh times.
Overall the x360 is a fluff computer and not a work station.
Yes you can run Pro on this machine. Yes you can run Pro on integrated graphics. But then again you can drive a car with both feet tied together and one hand tied behind your back.
I would not even touch the Thinkpad for this.
Both of these systems are exceptional in their field but are not designed for GIS work. And a 14" monitor is almost worthless.
If your willing to spend that kind of money get something more like this Dell
Model: I55777342BLKSKU: 5868313
And get a docking station and a pair of big monitors
