However, I was recently given the chance to switch to a laptop+OS of my choosing. I was eyeing up a thinkpad or xps, but I realized that I have no clue how I would facilitate the testing of Mac specific things like Safari and Apple Pay outside of a VM. Likewise, currently I have a 2nd windows laptop just for the sake of Edge/IE11 testing.
Folks who need to be able to test IE11/Edge/Edgium/Chrome/Firefox/Safari are you using VM's, juggling multiple physical machines, or have some other solution that works for you?
...into the datacenter (facepalm).
Except for that, what I found is that nodejs (and also python) development although seemed fast on a MacBook pro, but utterly sluggish compared to the experience on Linux, specifically Arch. nvm, virtualenvs, terminal and window navigation, file IO heavy stuff felt so much faster that eventually I gave the MacBook back and stayed on a Lenovo X1 Carbon.
Right now I have to access restricted systems, so a Windows10 VM runs (on two cores, 70% capped) 0-24h, but it doesn't seem to affect host performance and battery life much.
