Personal goal: gather ~$13,500 and buy the maxed out iMac Pro 2017 -- 4TB SSD, 128GB RAM, Xeon W (18 cores, 2.3Ghz, turbo boost to 4.3GHz, 42.75MB cache), 10Gb ethernet link, 4 USB Type-C ports, 4 Thunderbolt 3 slots, amazing display.
I view it as an at least 7 years of investment, if not 11-12 even.
(Especially now that macOS has a dark theme as well.)
I have a very keen interest in Linux and the people who make it happen... but reality is they are not dedicated teams of people working with high wages on Linux alone so problems with desktop always arise -- also competing standards, but the real problem is that a lot of end-user or specialized work software just can't run on Linux (3D modelling, architecture planning, professional design programs etc.). Truthfully, Linux on PCs is just fine but laptops are a whole different story.
I love Linux but for all its amazing engineering it remains a mostly programmer/sysadmin system and environment and nothing much else beyond that. I need a lot of stuff done outside of that and I have hobbies I wanna work on in the future and Linux just isn't cutting it. I don't want to hand-craft clever command-line configurations until I die.
Windows 10 is... I don't know, feels like it's going downhill overall. Important UX issues aren't being addressed for ages -- like the two sets of configuration UIs (almost everybody I asked says they were confused by that). WSL is good and useful, the cloud offerings look alright but something is just missing. Maybe the fact that after the April 2018 update the Mail program never managed to work with my mail again. Read about a "workaround" which involved resetting your user profile and... yeah, gave up. Who wants to restore their settings for a full workday just so a half-arsed mail program can work again? These things pile up and now I can't even tell you all my complaints nowadays because I never wrote them down -- only my accumulated impression, which is disappointment.
Windows is, in my opinion, descending.
