I don't recall asking you for an explanation of your belief system. Have a nice day.
Nobody asked you either, yet you shared yours ... because it's a discussion forum and everyone, including you and those whose opinions differ, get to post. Beware, I'm going to post an explanation of my belief system down below and I hope I won't be told off. You don't have to read it though, it's just a contribution to the general discussion and not posted specifically for you... ;-)
--------------------------------------
I for one agree with the "fear" (albeit fear is a strong word).
I had a perfectly working mid-2014 MBP since its release. Last summer, its 8 GB RAM started to get a little slow on large data sets and I began to entertain the idea of an upgrade. I planned to use my computer for another year or so, but I started to look at the new models, pricing etc, just to get an idea.
That's when I learned that the trusty chiclet keyboard had been axed in favour of the fail-prone butterfly. It's not so much the hassle of going through the replacement process that I feared (although I expect it would be pretty annoying to be without a working machine for that reason every once in a while), but typing is 75 % of my work. I run data sets and then type long analyses of them. I tried the butterfly keyboards in store and to me it felt like typing on a hard, flat surface. Like on a table. It was beyond uncomfortable, close to painful, on my fingertips.
So I expedited my Macbook upgrade. If I needed 16GB in the future, I would have to get it in a 2015 machine and their availability was fading. At the time, summer 2018, I called up Apple resellers all over German-speaking Europe, but none had a brand-new 13" MBP 2015 left in stock. Eventually I found a slightly used 1 year old 2015 MBP 13" with 16GB and jumped at it. I would have preferred to get it new from Apple and with Apple Care, but I felt like I had no choice and time has proven me right. I still keep my eyes peeled for a brand-new 13" 2015 with 16GB, but there are simply no new ones left in my country and I can't tell you how relieved I am to have jumped on the used 2015 when I had the chance. I'm crossing my fingers that the processor will be able to handle my tasks just fine for a long, long time. At this point it runs completely smoothly.
I have always bought Macs and iOS devices brand-new from Apple since 2009. For a long-time I was a hardcore fan and it's sad to say that this is no longer true. There is no devices in the current line-up that I fancy. Even the new iPhones are too big and too expensive for me (not because I can't afford it, but because the price-value-proportion seems totally off... it just wouldn't be a sensible purchase). The new iPads are so thin, huge and delicate compared to my trusty iPad mini which has a perfect screen (I think even the sharpest screen of all iPads yet), perfect size for mobile consumption, perfect reliability and sturdiness and a perfect price. Throughout the years I have bought 4 of them. The only Apple device I'm planning to get eventually, is an iPhone 8 once my iPhone 7 kicks the bucket, but that won't be the case for the next 3 years or so. I can't say that I'm lusting after any of the new Apple devices and that is really strange for me.
In my case, I would diagnose this as "#MacbookFear" paired with an overall "#AppleFatigue". ;-)
