1 technically as my wife killed a MBP and needed a replacement so got her a 2019 MBA for Xmas. Already told her the keyboard is likely to die, but at least it's the 'latest' (bad) keyboard variant.
None for me. Not just the keyboard, as except when I'm traveling, my MBP at home office and work office is generally sitting on a stand plugged into a 38" UW display at home, or 2x 27" at work + external KB and trackballs in both locations.
The combination of touch bar w/out physical escape key, lack of a 32GB RAM option, mediocre CPU upgrades (partially on Intel) had me choosing between a new 2016 MBP and instead I bought a lightly used 2015MBP. The subsequent years had nothing I wanted to give Apple $ for until the MPB 16 which I'm typing on now, with my gripes vs the prior years all removed finally.
Watching my wife's MBA carefully, but she's at least better at not eating at her desk, unlike me..maybe it'll help.. 😀
