Stock minis are absurdly bottlenecked by hard drive performance, to a "what was Apple thinking?" degree. The 5400 rpm drives are the slowest I've ever experienced, and the fusion drive is an improvement only for people manipulating lots of tiny files (mp3, web browsing, word docs, etc), but not for photo editing that is thrashing GB worth of data. The drives decay seriously over time, not just from becoming fragmented (which you can fix with a reformat and restore) but from remapping bad sectors to the innermost, slowest part of the drive platter. It's not uncommon for one of these machines to take several minutes to boot and show the self-diagnostic progress bar every time.
The good news is, a current (2015-2016) SSD makes these minis feel like completely different machines. You would not believe the difference it makes. They are in no way obsolete, they just need some new drive love.
Again, the fact that they put such a pathetic drive in a device costing $800 starting price is absurd. You seem to be simultaneously knocking Apple while defending them...
