Hmm, last one I promise, for now

I have been doing a lot of research lately on Windows Phone 7. On the one side, people are evangelising it, on the other side, people say Stay away from it.

What are the real advantages ( for me ) to buy a Windows Phone? What makes it stand out? Howcome it is so expensive in South Africa?

OK, the last question is probably not really answer-able, but I'd just like to know from you guys / girls what really to expect from this phone.

Thank you again.
