I don’t buy a replacement computer
To get fewer features. Changing I/O ports, no SD slot etc makes the current model less attractive than what came before (although an 11” MBA has not has a SD slot for at least the last 3 years).
So far as running Photoshop on an iPad...ok, and the rest of the adobe suite? Hook it up to a calibrated monitor? What if I do a teathered capture? Oh...no port for that. And what if I use Capture One rather than Lightroom? No port to IOS for that...
Someday a tablet could be designed with the proper ports. With RAM and GPU capable of manipulated a >60MP image, connect to an external monitor, network and storage system. It would be a bit bulky...maybe you could permanently attach the keyboard so it could also serve as a screen protector.
Then, you could call it a “Laptop”
F’kin idiots at Apple....
