I am looking to buy a Mac Mini as development server. The main development work will still be done on a conventional Linux/Intel based machine, but I need a Mac box to ensure cross-OS compatibility throughout the development process. The Mac will be sitting in a corner of the office, running build and test routines when necessary, but most of the time it will be idling. Therefore, performance is not a critical issue, but price and a long life span is.
Apple just recently launched their M1 processors and the newest Mini models are shipped with this AMD based CPU. What is your opinion. Should I settle on one of this new CPU developments, or is a somewhat older Intel based model a good enough investment for the coming years?
