The popular dust complaints aside, a brand new machine has immediate problems for someone whose palms tend to touch the newly enlarged Force Touch trackpad during typing, a hand position I got used to with my Macbook Air 2013. Typing on the new design will cause repeated keystrokes, delayed or missing keystrokes, and instant cursor shifts during typing that make it so I need to approach the keyboard in the same way one would properly play a piano in order to get any meaningful work done. Great if you're a trained pianist, terrible if you want to get actual work done from a coffee shop where you don't have a stand or external keyboard on hand.
Apple knows they messed up with the butterfly mechanism and seem to be fixing that in the next design. In the meantime, there are a few things they could do now through software to alleviate these issues:
1. The ability to remap the Force Touch trackpad tracking area in Settings. Being able to remove 10mm from each side would fix my cursor shift issue. People currently use tape to solve this... on a $4000+ machine.
2. Ability to set a numeric value for Force Touch sensitivity as opposed to 3 constant values with a much higher threshold than is currently being used as "high".
I know Apple is all about limiting options for a customer's own good, however, these software changes would go a long way in helping people debrick an expensive laptop who don't happen to fit whatever hand size their QA team of classically trained pianists have.
