My first reaction when I saw the touch bar was "Ugh this is going to cause a world of headaches when runnning Ubuntu". I was relieved to see you can still get a MBP with physical function keys[1]. (semi-off topic: any Linux users want to chime in and recommend a 14" or 15" laptop with build quality similar to a MBP?)
