What is poignant here, is that I haven't seen a post from anyone who bought the iMac Pro for business complaining? Most of the criticism appears to come from those who never owned one or never needed to?
I'm not sure what they are meant to be complaining about regarding the iMac Pro itself. It wasn't a bad computer
if it met your needs. Sure, we'd got to the stage where it either needed to be upgraded or discontinued - and now we have the answer - but that's hardly a surprise when we know that the whole Mac range is going to be replaced by Apple Silicon over the next year or so (which, amongst other things, will completely change the Core i vs. Xeon dichotomy which was the main distinction between the iMac and iMac Pro).
The main reason people have been complaining about the iMac Pro (and Mac Pro) is that they
don't meet their needs and/or budgets - whether it is pro/business or enthusiast - so why
would they have bought one?
However, there has a bigger picture problem with Apple's pro desktop since about 2012:
2012: After 2 years without an update, "classic" Mac Pro gets a very underwhelming spec bump that causes a mass of complaints. In the EU, the classic Mac Pro is discontinued, with no news of a replacement, because Apple can't be fussed to fit a fan guard to meet a safety regulation that has been in the pipeline for years...
2013: Apple launch the radically different trashcan requiring users to have a complete rethink over peripherals/internal expansion, and making performance highly dependent on support for GPU-based computing... and if you needed time to make that transition, tough, because the classic Mac Pro has
gone folks -
long gone in Europe.
2016-17: If you did buy into the trashcan, your business lease is running out, time to re-equip with the latest Mac Pros.... which, oops, don't exist. Same specs as 2013 (beyond moving the entry-level up a notch).
2017: Apple admits the trashcan was a mistake - vague promise of some sort of "modular" Mac sometime. iMac Pro announced (not available in quantity until the new year) which is fine and dandy if you wanted an all-in-one, useless otherwise.
2019: Mac Pro announced (don't expect to get one until 2020)! Hooray! Except it starts at ~2x the price of the previous Mac Pros - and that's for a pathetic spec. Real starting price is $10k+.
2020: Your iMac Pro is coming up on the 3 year mark... no replacement in sight. Pretty obvious at this stage that the iMac Pro was a dead end... then Apple announce Apple Silicon so, Hallelujah, the
Mac Pro you got in January is now a dead end, too...
So, in summary: every pro desktop Mac since 2010 -
including the 2019 Pro - has been a one-model-wonder with no upgrade/replacement path that doesn't include a radical change in specs, workflow and budget. Now, that doesn't mean that your Mac becomes useless overnight - I'm sure people will be rocking their Mac Pros for another decade, just as people are still rocking their classic <= 2012 towers - but it is a headache as soon as (e.g.) you add another employee, get a computer stolen or your accountant tells you it's the tax-efficient time to buy kit or re-lease, because you can't just drop in an incrementally better system: you're talking major workflow change and forced major OS upgrade.
I suspect that the practical upshot of that is that any business user
for whom those things mattered has already left the building and switched to PC. Those remaining are either (a) Apple enthusiasts prepared to walk over red hot coals to stick with their brand or (b) more understandably, people who are so heavily committed to Mac-only software to the extent that the risk, time and re-training needed to switch to Windows or Linux outweighs the hurdles that Apple throws at them. Oh, yes, and those users for whom all-in-one machines like the iMac just happen to hit the sweet-spot.
Trouble is, short term you can milk more cash out of your captive users by hiking prices and that looks good on your quarterly results. ...but in the long term, if you don't try and grow a market by attracting customers from your competitors, it will shrink it means the stagnation and slow erosion of the Mac user base. And, sure enough, there have been several years of results from Apple showing fairly stagnant growth in sales but huge gains in revenue (although the last year has seen a huge boost in laptop sales, I'm not sure that's shown up at the pro desktop end).
The other clue: look at the Mac Pro section on Apple's website. See all the performance comparisons with comparable pro apps on Windows? No? Exactly - but there are plenty of benchmarks showing that the Mac Pro is
much faster than your 2013 trashcan. Pretty clear who they are selling to...
Edit: I'm really hoping that the Apple Silicon move will make Mac unique again and reverse this a bit. Also, some of the design & pricing decisions starting with the 16" MBP suggest a sudden outbreak of common sense, too.
