I'm sharing a 13 MBP with my wife but both have iPads respectively(11 Pro w/ Smart Keyboard Folio and the Pencil for me and mini w/ the Pencil for her). MBP is now used only when doing something iPad can't do because of superior UX and easier system management. Also, the main place to use computers is the sofa and bed as there is no working desk in our apartment.
The frequency in use of MBP has been getting lesser since the enhancement of iOS/iPadOS, including moving main data storage and backup destination to iCloud from local Macs.
After retiring from the IT industry, I have no tasks require MBP(wide web browser screen for management console of AWS/Azure, terminal app, rich feature set text editor and so on for self study) anymore. So I have been using the MBP just for system management(keeping battery status healthy, system update, trouble shooting reported by her) as IT helpdesk of my home since then.
After a chat with her, she only needs MBP just for foreign language study which requires the HW keyboard. It's less than 10% time of her time out of entire computer usage. We realized this can be replaced with iPad w/ HW keyboard.
I almost decide selling MBP to buy a refurbished iPad Pro 11 for her, and sharing my Apple Pencil and Smart Keyboard Folio. Now I'm in final checking if I miss something requires MBP, also looking to see the release schedule of next-gen iPad Pro.
