Earlier quoted context omitted.
The new MBA has touch ID though, whereas the entry level MBP doesn't. The convenience IS a lot of value for some people.
Do you think it's worth it over the entry level MBP considering the difference in the CPU?
It is nice to use Apple Pay from my Mac -- the twice I've done so. I could always have opened the page on my phone and use its sensor instead.
Other than that, moving my hand up to the corner isn't much faster, if at all, then simply typing my Mac password which is pretty well wired into my fingers anyway. In fact I had made a small config mod to use the touch sensor to authorise sudo, and in the end I undid it because typing was faster. And my watch unlocks my Mac most of the time. So a nice to have, sure, but not as revolutionary as it was on the phone.
