That’s not good. I have the 16” MBP and it has been great. It’s being sold though. That leaves me with an iPad Pro, which is fine, except I can’t do everything on it. Now I wonder if I should return the iPad Pro and get MBA or something.
I imagine (and hope!) the negative experiences are overrepresented on the forum and are outliers – and that when you get yours it will just be great, period, and you won't have to worry about it.
The things that are good about this iMac, are absolutely incredible. It is just blindingly fast, does not skip a beat, and the display is amazing. I briefly had the 2019 i9 and the 2020 i7 feels substantially snappier and smoother in every respect. It's a great machine.
There are a few things on mine which should have been caught by QC which is slightly concerning, but in the grand scheme of things, they'll probably be fine. None of it was enough to warrant a return. I'm just a little frustrated because I probably expect too much from Apple based on my previous positive experiences and I don't particularly like the possibility that something might go wrong, leaving me without a computer for an extended period of time. I don't think I'd be as concerned if the service options weren't limited and slowed down by the pandemic.
