If you ever got to use the Mac emulator on a Mac XL - it highlighted how fixed Mac gui layout fit the 9” Mac screen like a glove. The extra screen resolution on the 12” screen was there but the menu stopped at the 9” mark. I had a Mac XL for a while but traded up to a Mac II when a/ux became available. A happier time in computing.
