I generally agree that you shouldn't have to look at the keyboard, but I'm currently hoping that peripheral vision plus muscle memory will be enough to make up for the lack of tactile feedback when it comes to commonly used applications. (I haven't tried out the new MBP yet, and I'm going to do so before ordering, but that's my hope.)

In return, I'd get the ability to use slide controls, and have both system controls (volume, brightness) and application-specific ones directly on the bar rather than having to choose Fn for one - which makes for terrible ergonomics. Plus, Touch ID.

But then, I don't care about the Esc key because I've had Caps Lock mapped to it for years.
