I dont see Blackberry users, iPhone users or Android users changing.
My wife has a year-old blackberry and wants to drop it for a WP7 phone. My son's iPhone took a dirt-nap and couldn't be revived - he's using an old 'dumb'phone and waiting until next year to choose his next phone because he wants to test out WP7. Two of my coworkers purchased Android phones in the last 3 months and both have said they'd probably have bought WP7 phones if they were available then.
Of course I also know many people who are completely satisfied with their iPhone, Blackberry, or Android phone. I agree that another major OS in the market will probably just help out the consumer. Give me some good old competition!
How so? Wouldn't Apple repair/replace it?

Not announcing. Giving an opinion.
