I compared the 15's speakers with the 13-inch MBP Touch Bar. Touch Bar and Touch ID: this has been covered ad nauseam but...here goes. Jumping between tabs on the Touch Bar is useful, though I wouldn't go so far as to say essential. Touch ID: I use the Touch ID on the MBP, just like I do on my iPhone and iPad. Touch ID is a great addition/convenience for any Apple device and it's a big reason I use the Touch Bar -- and another reason the Touch Bar is not a gimmick.
