Needing a dongle "here and there" means that now I need to carry it with me at all times. And that means both USB-A and HDMI dongles. More things I need to worry about to make my 3500EUR machine useful. This is a clear usability regression and the "USB-C" only future doesn't seem to be happening until end of lifetime of this machine.
The keyboard feels bad and my space has started failing. This is also a clear regression with no benefit over previous model.
Touchbar is still useless with pretty much no features over function keys (excluding TouchID on the power button). Pretty much no 3rd party apps use it well and the fact that it can't hold global app shortcuts make it significanly less useful than the previous keys. Another clear regression.
It's not that the new Macs are bad machines, it's that Apple made a few baffling decisions which make the user experience worse over previous models. With pretty much no benefits.
