Now, if WP8 also include some more functionality, both HW and software, more of what I'm used to with Symbian/Maemo/Android, then there is no objective reason to not accept it as a good state of the art OS. Not for anyone.
The only reasons for not liking it will be of the philosophical and/or emotional kind.
But, as with the Amiga, you never now. I would be very surprised though if 1. WP8 does not gain a decent market share. 2 Nokia does not again become a profitable company.
