This is why I would like this:
- Almost all my services are tied to my personal Microsoft account because all of these "productivity" things I do are for my own benefit.
- I don't want to tie this service to my work account. Case in point: I left my previous job in December, leaving behind an Office 365 account tied to a number of services.
- I don't want to tie this service to my school account, for the same reason as the work one.
While I do use Wunderlist, OneNote, Pushbullet etc for work and school purposes, I use it to run my household as well (and my life). I may change jobs/schools, but my Microsoft account stays the same.
