This I think is the Windows perspective. The Linux perspective (Debian in my case) is somewhat different:
- Hardware wise the Trackpad is identical in performance to the Mac. All the same gestures are recognised - but the software doesn't use most of them. In fact the software side was terrible until libxinput took over from the old synaptics driver. Now if it works, it works well - but it's still a little lacking on the gesture front.
- Coil whine should be no different - but I've never heard it.
- Fan control is perfect, which is weird. Maybe it was old BIOS?
- Intel's GPU firmware & driver has been a 18 month long cluster fuck. It's the same cluster fuck on Windows and Linux. It still isn't perfect, but it's much better. At the rate they are going, they may get it right 2 years after the initial release of the CPU. Here's hoping. I don't know how Apple could escape this mess. Maybe they knew they couldn't, so escaped it by not upgrading the CPU's for donkey's years.
- Oddly the wakeup problem happened on Linux too. Once I opened by bag and it was so hot I though I'd destroyed it. The issue has gone now.
- Linux has the same issues a Windows when it comes to mixing HIDPI and normal displays. In Linux it's a fundamental limitation of X. It can be fixed in Wayland.
One piece of advice: update the BIOS religiously. At least until Intel fixes their Skylake GPU issues.
