I tried that and got an HP Spectre 15" when my 2013 rMBP was having memory issues. I really wanted to like it and it was a beautiful machine, but the home/end key was in a weird place, and the zoom/scroll in the browser (Chrome) is still clunky, especially the zoom, compared to Safari. There were other little things like no right click dictionary, poor palm recognition, etc.

I went back to the 2017 rMBP and really like it. I use Windows in a VM and have the Cmd -> as end and Cmd <- as home and it works great.

I'd still buy a Thinkpad if they put their old keyboards back in service.
