Here are my issues as a user of a 2013 Mac Pro:
- Neither the Mac Mini nor 2019 Mac Pro are user-serviceable; you have to take your Mac to an Apple-approved repair center if you want to upgrade your RAM (see https://support.apple.com/en-us/HT205041#one and https://support.apple.com/en-us/HT208377). I guess it's nice to have DIMMs when the computer is out of warranty, but I'd like to preserve my warranty and not have to pay Apple's prices for RAM upgrades plus labor costs.
- The storage is soldered onto the motherboard in the Mac Mini, which precludes upgrading or replacing storage.
- The storage for the iMac Pro is a special proprietary design, precluding the use of industry-standard M.2 NVMe flash drives. (Granted, the 2013 Mac Pro doesn't use industry standard M.2 NVMe drives, either, although I've read that it's possible to use some standard NVMe drives in the 2013 Mac Pro with the help of an adapter.)
- The iMac Pro at $4999 is still much more expensive than the previous generation base Mac Pro, which was $2999.
- The iMac Pro is an all-in-one design. I prefer desktop computers that are not housed inside a monitor; what happens if the monitor fails?
