I dont know about Ubuntu, but on my Fedora 29 install most of these are not an issue: >ugly fonts I dont have a problem with ugly fonts. Default fonts in Gnome F29 are nice. I use it for dev/devops work, not graphic design so my stds are not exact. Could also be I don't know what a "pretty" font is ;) >the lack of good touchpad support, Mac touchpads have always been vastly superior to others. However, the TP Carbon X1 has a really nice touchpad/feel to me...close enough. >the wonkiness on connecting external displays, I don't have any wonkiness via chaining 2 external monitors via TB3/USBC - this might be a combo of better hardware in the TP? >the lack of good color calibration, not in graphic design so i can't comment here >iffy power management, Not sure what you mean here. Latest Fedora + maybe tlp is enough for me to get mac/windows type batt life. Sleeps fine/ wakes fine etc. no issues on TP Carbon X1 (or previously on T47x series) >and lack of rootless/SIP AFAIK this is a pretty unique feature to macos
