I have a 2018 15" MBP with 32gb of RAM. So far, knock on wood, it is acting fine. I am going to buy AppleCare+ immediately now after reading these comments. I feel even more ripped off though. This doesn't include the $300 I had to spend on an OWC TB3 dock to be able to connect my other drives, wired ethernet, etc.
I bought this machine because my entire workflow has been Apple for 25 years and the thought of switching is overwhelming. I have tried to go "cold turkey" before and switch to Windows and I just can't get used to it. For a few things yes.
However, I am more determined to try and get out of Apple's grip. So, I am moving parts of my workflow to Virtual Box VM's and slowly adding more and more until I get comfortable, find solutions, etc. Hopefully by my next laptop purchase I can find a non-apple machine.
The touch-bar is pointless. I hate it and don't use it unless I have to. The keyboard still feels weird to me. I tend to use an external keyboard and mouse.
