Is that a correct speed test, or just an illustrative picture taken from elsewhere?   If so, both the 13" and 16" MacBook Pro handily
outpace it, which is strange for an otherwise more powerful desktop.   Even Thunderbolt interface external drives are faster.
Further, is there a difference in SSD speeds for the various sizes (256GB to 8TB) available?

No idea what that screenshot is meant to represent. As the figures were so low I thought it was an externally connected TB SSD which was mentioned in the text above but perhaps it is the 256GB model or something else entirely?

My 2020 iMac with 512GB internal storage tests around 2600MB/s for both read and write, although that was soon after did a migration so some indexing may have been going on in the background to slow it down a little. For comparison my 2019 MBP 16 with 512GB storage achieves 2300 MB/s write and 2800 MB/s read.

If developers can make Windows run on a Pi4, I’m sure Parallels can do it as well. 

99.99% of people who need to run Windows, need to run the x86 version of Windows, not the useless ARM version.

Is the RAM still user upgradeable? Because £600 for 32GB is to put it mildly...”cheeky”.

Yes on the 27" models. 8GB (two 4GB) of 2666MHz DDR4 memory; four SO-DIMM slots, user accessible

Is this a new phenomenon with a recent MacOS update or has it always been a problem?  I guess I’ll keep an eye out,

Only a problem with 10.15.6.

I'm not sure there is a fundamental design issue with the butterfly mechanism itself, just that the travel was too small which didn't allow any dirt that got into the mechanism to get out again. Making a scissor mechanism with only 0.5mm of travel would probably result in the same issue. They should have increased the travel which would have made it more reliable and much nicer to type on too.
