I've been using the new Mac Pro since 2015 and it's served me will without the need for upgrade... except for one thing. The primary disk being only 256GB causes me all kinds of issues. Everything wants to install and save there and there's no simple way to offload stuff to a secondary disk, so I'm constantly moving, symlinking, etc to keep enough space free so that my computer doesn't crash. Very annoying. This could, of course, be solved with software.
