I disagree. There is a place for the Fusion drive when maximum storage for lowest price is needed, with better performance than a straight HDD. That place is not everywhere and it doesn't work well for many use cases. Heavy LR users would seem to be one of them.
With any sort of luck, SSD prices will drop over the next couple years, and then we won't need spinning rust for anything but specialty usages.
I think a fusion drive would be a very niche purchase if people were educated on them a little more.
An SSD is just so so so so so much nicer and unless you need tonnes of storage on your device and dislike external hard drives, I struggle to really understand how in 2018 a company such as apple can price their devices so extortionately yet offer tech from so long ago.
