Depends what you use it for. I've currently laid up my 2011 27" i7 3.4GHz quad-core iMac ready to sell, and I'm running my home studio on 2010 Mac Mini running High Sierra and Logic Pro 10.4 with a 512GB SSD and 8GB RAM. The sheer computing power inside a modern iPad will wipe the floor with my 11 year old Mac Mini, yet I can get more done on the Mac Mini because it has a desktop-class OS running pro-grade apps.
So, horses for courses.
Well said. In fact, the iPad as laptop replacement thread with thousands of posts on this same board has plenty of additional examples where one just cannot replace the other.
Plenty of the PDF documents I need from the Canadian government can only be downloaded or edited on a Mac or PC with Acrobat, as an easy example. So in my life even though iOS is the platform for most things I do outside of work, I’d still need to have a conventional Mac or PC in order to get basic things done.
