Storage tied to the MB is bad for an desktop / laptop. Also 2 cards forced into an raid 0 is just as bad.The days of letting us "under the hood" are soon to be long gone. Very basically the need for security and enclaves will continue to grow and this coupled with more component compression on the chip will essentially render all gear "inoperable". So as time goes more layers of superficiality will be offered instead of peeling the layers back.
The software itself ... well Apps really ... seem to have diluted my interest as you're being directed by Apple through the App store for just about everything ... the search and conquest for specific software that piqued my interest is now gone - if it doesn't come bundled with the things I buy I'm probably not going to mess with it. The "geek has been replaced with meek".
The next mac pro will need m.2 slots and maybe at least 1 HDD / SSD cheaper non pci-e slot.
