I use an iMac when I’m sitting/standing in front of a desk.
My portable computer is an 11″ iPad Pro. I don’t carry a MacOS laptop anymore.
But occasionally something will come up when I’m on the go and I need do something that isn’t possible with iOS and I need MacOS.
Thankfully Screens meets this need quite nicely. I simply tap on Screens on my iPad and it connects to the Mac back home. Then I get the full Mac experience over the network on my iPad.
You do need a reasonable internet connection to make this work nicely. But I’ve used Screens successfully over LTE and also public Wifi hotspots without issue.
Highly recommend it if you want to make the move to the iPad.
