I've pre-ordered a new 13" MBP with the Touch Bar. I think it could have some pretty cool functionality, and I'm willing to see how it evolves. I've had resistance to some new Apple "innovations", but over time found them to be useful. Independent of the Touch Bar app functionality, I love the idea of being able to login/open my MBP with fingerprint ID. My single biggest hesitation to the Touch Bar is that I currently use a utility called Spark that turns the Fn keys into application launchers. For example, F12 opens Polymail, F11 opens Fantastical, F10 opens Chrome, etc. This is the fastest way I've found to switch between applications, and it really speeds up workflow. Every other method of switching between apps I'm aware of requires at least two button presses or use of trackpad or mouse. For example: Command-tab to scroll through applications (at least two button presses, often more) Alfred or other application launcher: command-spacebar to invoke, then start typing application name (multiple presses) Activate mission control with 3 finger swipe, then choose application All of these methods are way slower than what I described above. I'm wondering if there will be a way to configure Touch Bar to continue using Spark with Fn keys. At the very least, my guess is I'd need to use a modifier key to display the Fn buttons on the bar, which would add a button press. I suppose I could order the MBP without touch bar, but then I'd lose out on fingerprint ID as well as some of the potentially good Touch Bar features.
