Framework sells keyboards for the Framework 13 for ~$30. I can find a Surface Go on sale for as low as $500.
No, I don't think anyone's going to throw out a $500-$1000 device because it needs a $30 part and maybe 15 minutes of work (steps here: https://www.ifixit.com/Guide/Framework+Laptop+12+Input+Cover...) and they could instead replace their laptop with a tablet for a mere $470 more.
