Let's see, what does the past 18 months look like? New Mac Mini, new iMacs, new iMac pro, two upgrades of MacBook Pros, new MacBook Air, new OS, and new Mac Pro and new monitors soon to be released. Yep, no love there at all. LOL.
It's not that they've released items in the Mac line, so much as what they've done to said lines.
The Mac went from the most flexible, connectable, upgradeable, and reliable machines in the know computing universe (2011) to some of the most unreliable, un-upgradeable, un-serviceable, disposable, adapter-heavy machines sold today.
Not to mention more expensive than EVER, while providing less features.
Of all the machines you mention, the mini is probably the least offensive here (and the only one I'd recommend), but they STILL managed to solder it up.
Let's see what the so-called Mac Pro will look like.
