I haven't abandoned ship yet, but am adjusting my workflow in that direction. Weirdly, I've spent more on Apple hardware in the past few months than the past few years. I got the ipad pro, the imac and a refurb Mac Book Pro - all for specific reasons and in spite of Apple.
The only machine I'd keep right now would be the ipad Pro because I love Procreate so much.
The iMac I bought because for the combination of screen, ram etc it worked out to be equivalent. I really wanted a 5K screen and couldn't find a decent Windows alternative. The fact that I could add my own Ram to this one was the dealmaker. However, as much as it is a great machine, I resent everyday its lack of ability to be mounted on a vesa (I didn't want to gimp it on purchase by buying the vesa mount option). There are some incredible arms available now (Ollin!) and the fact I can't use this machine on these, and the fact that it is always at slightly the wrong height depending on my position, means I can't love it.
I bought a 2019 13inch Macbook Pro, and while I realise it was the base spec, I was shocked by the low quality - it was unpleasant to use to its heat and the electric 'jizz' (-no grounded power cable provided). I returned it and bought a second hand 2015 MBP because, having the iMac and iPad, right now, having an Apple laptop makes sense. But that was not a decision based on anything other than minimizing inconvenience.
I like the ipad -but most of that is because I am so enjoying Procreate. There's nothing else on there that I wouldn't be happy to use on a different device. For example, I'm deeply unimpressed by the fact that I have to spend about 30 seconds scrolling the page up each time I neeed to get to my latest email.
I've switched my notes to Apple's notes app and hate it - I can't have two separate windows etc.
On all my devices, I don't appreciate having notifications nearly everyday telling me to update to Catalina / 13 everyday etc.
And trying to maintain my parents' Mac Mini with the spinning HD - OMG!
Oh Apple ...
It all seems so unneccessary - Apple could just give their customers a little bit more and stop nickel and diming - like they used to...
Anyway, I'm adjusting my workflow so that in a year or so, all of these machines, and the phone, will be switched.
I certainly can't say that the grass is greener. I've tried many times over the past few years. I have always had Android and Windows machines at the same time but stayed mostly on Mac. This time, however, it feels like it's time.
My experience with the MBP really shocked me - it felt like a cheap knockoff of a Macbook Pro. I'm typing on a 5 year old second hand machine that feels like a different world to a machine built this year. It's quiet, cool, has buttons that feel good etc etc.
