The need for 16-inch iPad
Advantages of 16-inch iPad
Apple is known to fit massive batteries in larger housings, so a 16-inch iPad is good news for battery life. Another advantage is the possibility of the bigger, better display with a high refresh rate.
There are rumors that the 16” iPad will run on the lighter version of macOS, and it is already in development. Can we expect macOS on iPad? Time will tell.
