Essentially I'll be getting the same build: 16GB RAM, 512GB SSD. I'm just up in the air as to whether I should get a refurb 2018 model with a 2.7GHz quad-core i7 or a new 2019 model with a 2.4GHz quad-core i5. It will be mostly casual use when travelling -- maybe some light virtual machine use (retro VMs like Windows 98, XP or a Linux distro). The refurb would be only $12 more than the 2019 version. If anyone has any suggestions one way or the other, I would certainly appreciate it!
