Never a budget option?
I am typing this on my late 2012 unibody MacMini. I bought it just before they refreshed the line in 2014 and made it far worse... no quad-core option, less upgradability.
It cost less than £500 for an i7 with 8Gb RAM (which I upgraded). That was a bargain really for a Mac.
So what does the new one get me for all the extra cash? 1Tb SSD as standard? Proper GPU? And can I still upgrade the disk and RAM or have they dropped that feature? Mine is a little erratic and I have thought about replacing it so this is good timing - but for "comfortably over £1000" maybe I might as well get a MacBook or iMac?
