I use my 12.9" iPad Pro for watching video content during my morning treadmill run and before bedtime, drawing in Procreate with my Apple Pencil, answering email, surfing the web, reading e-books and e-magazines, looking at my photos collection, playing with GarageBand and some synthesizer apps, and listening to music. I use my 2019 27" iMac for "heavier" apps like Adobe CC, MS Office, Logic, and some other photo-editing apps. I recently gave my 2015 MBP to my dad, thinking my iPad Pro with Magic Keyboard would replace it as a secondary device when I need portability. It suffices for most things, but I miss having portable access to my Mac apps, so I'm thinking of selling my iMac and getting an M1 MBP.
