If you can get past WP7's messy tile screen and app list, then I say why not wait for the WP7 phone? WP7 already has many good apps and you can sleep a good sleep not worrying about non-support from NOK. But sorry it's not for me, I never tried it in person, but my head aches everytime I see the tiles fighting with each other for my attention... IMO it's a better design concept on tablet/PC due to screen size.
