The Geekbench results for my phone (3 year old iPhone 12 Mini) do suggest it might actually be better than my 15" 2014 Macbook Pro, which at the time was about the fanciest you could get. Just 6 years of progress! I imagine the latest round of iPhones are even better, particularly if you go for the enormous ones. But, meanwhile, my Macbook Pro can drive two external displays, as well as having a good size internal display of its own that will still be useful. It's got 2 standard USB ports, for connecting keyboard and mouse. Add USB hub, and you have even more options. It has fans inside, so it can run at full tilt for quite a while before hitting any thermal throttling. 16 GB RAM means it's feasible to run a VM - and, since it's an x64 system, it can be persuaded to run many x64 OSs natively. One example would be Microsoft Windows, which you may have heard of, and which has been ported to x64. The UX without any extra devices is fine as well. As well as the nice built-in display (which is a good size, and >200 dpi), it also has a solid inbuilt keyboard and a very useable trackpad. For all that I do much prefer a proper setup on a desk with a full-size keyboard and a mouse and a nice set of displays, the UX for general use without any peripherals is quite reasonable. Also, it has a headphone jack.
