WP7 might still be a bit young, but we know some of the major features that are coming, it was said before by someone else, but it ISINT going to get worse before it gets better.
and if you dont mind playin with it some, they will already do a lot. Id go with it now and watch it get better as it goes, otherwise it might be a while before you get to switch later, with contracts and all
