In a perfect world I am sure there are a ton of us who would love to have a refreshed version of the 2014/15 MacBook Pros, but unfortunately that is not reality. Technology is always changing and we have to choose what is best for each of us based on what is available.If the MBP2018 were like the 2014 rMBP 15", no complain. I would have bought it. The main issue is I have tried the 3rd gen butterfly keyboard several times in different stores but I can't seem to like it. As you said, why spend that much money on a laptop that uses that keyboard. Perhaps I just try out the Thinkpad and if I don't like it, then return it and just buy a MBP. At least the Thinkpads have a better keyboard.
To what others have said, based on prior posts that you have made, it seems that a MacBook Pro is not a good fit for you. I believe (correct me if I am wrong), but you have already purchased and returned at least one unit. You need to really look at what you are needing a laptop for, and how it will best suit you. Perhaps a Dell XPS or any of the other high-end models are good. But no machine is perfect. Just some are better suited to certain individuals than others.
Also, I use a Thinkpad for work, and I can tell you the same thing that @Newtons Apple said, they have their own host of issues. And their build quality is nowhere the same as a MacBook Pro. Not saying that they aren't a great notebook and might suit you well. But again this is my opinion based on my use.
Ultimately you will have to make compromises somewhere along the line, but pick a machine that has the strengths you truly need and the compromises you can live with. And most importantly, don't stress so much on all the negativity; being truly honest, it is not worth stressing so much about the issues of a computer on a machine you will likely keep less than 4 years anyways. If you legitimately buy a laptop and it has a serious issue (i.e. keyboard, CPU throttling, or other), that's one thing, but constantly posting about issues related to a machine you may or may not buy isn't going to help you make a choice, or help change the way Apple makes their computers.
