I can certainly sympathise with some of the points
@LambdaTheImpossible makes. The original post was quite thought-provoking, and caused me to wonder whether, all things considered, I am still happy with the Apple kit I own and have owned over the last 15 years. My conclusion is that I am, very much so. So perhaps I might offer an alternative view?
There have been times when I have felt mildly peeved by Apple’s prices and some of their products’ idiosyncrasies. That said, with a combination of 2008 and 2013 Mac Pros, a 2012 retina MacBook Pro, several iPads and, to some extent, a 2019 MacBook Pro, things I’ve happily done include some fun computational number theory on GPUs (quite rudimentary perhaps, but pleasing to me), using Mathematica, prototyping code for real-time capture & analysis of network traffic data and amusing myself with a variety of Python projects. Along with all of the usual, mundane “productivity” stuff, trying not to spoil my photographs in Lightroom or PixInsight and spending far too much time reading and playing chess on iPads. Using LINUX virtual machines when appropriate (including, in an act of extreme silliness, to run APL on Ubuntu/390 in Hercules in a Ubuntu vm). I find the ability to use such a range of software without any real difficulty on a single platform rather amazing. Perhaps I am unusual in not needing Windows (not even under Fusion or Parallels).
Could I have done all this on a mixture of Windows and LINUX machines? Sure, and I would probably have spent less money. Was the 2013 Mac Pro perfect? Far from it, and I realise that for some purposes it was a pretty duff design. The 2019 MBP seems to get hot and to spin up the fans far more than I would like. But I have been able to do everything I wanted — and I still can — without drama and with no hardware problems aside from, eventually, after seven or eight years, cooking the dGPU on the 2012 rMBP (which was probably my fault for treating it like a workstation and letting it get too hot too many times). Oh, and the rMBP needed a new keyboard when I dropped it on hard ground when using it outside in the dark with my telescope. I rather think that was my fault, not Apple’s. It still worked, though (and didn’t mind the dew).
So, overall, I’m pretty satisfied with what the kit has enabled me to do and, perhaps more importantly, with what I have learned using it (although, given how long I tend to keep computers, I’m probably far from the ideal customer; I’m still very happy with my iPhone X, for example). And I am happy not to use Windows. I’m quite excited by the prospect of buying an M3 Max or Ultra machine soon (possibly very soon ….
) and am confident that I will get plenty of enjoyment from that, too. That doesn’t preclude the possibility of getting a reasonably high-end Nvidia GPU to experiment with although, given that even the M3 Max’s GPU will be four to five times more powerful than my currently machines’ GPUs, I may not bother with that for now. The kit I have been fortunate to own has been more than good enough for me and, as I haven't had major problems, there has been no compelling reason to change. For me, life is too short to spend time worrying about whether the alternatives might be better (even though, in some respects, they may be). YMMV.
