My 2010 Mac Pro is still running well and does what I need, but it’s only a question of time before it needs to be replaced and a top spec Mac mini is the most likely contender. The current mini is a good machine from what I hear but that is not enough reason to ditch a computer of proven reliability.
After reading a couple articles just now it seems likely that Apple will be introducing their own processors in 2020, which tend to run cooler than Intel and rapidly catching up for speed. Indeed the iPad Pro already uses Apple processors and likely to out perform the MacBook Pro before long.
Having used Macs since the last century before OS X even existed I well remember the software difficulties when Apple switched to Intel and I would hope they would be better prepared this time for a smooth transition, however I am left wondering if anybody has some insight into how existing software like Blocs will run on these new processors or will it create a nightmare for developers and users while bugs are patched.
Knowing the way these things go, if Apple switches to their own processors I can imagine them placing more emphasis on compatibility than with the Intel processors, which may be a nasty surprise in a couple years time for anybody who has just bought a high end Intel based machine.
