I have been using HTC Surround WP7 for two years. And I made friends along the way. None of them cared to ask what my phone is (although I don't put my phone out during dinner, dinner is dinner). And now I got a Lumia 920, they say, nice phone and they have seen it in ads.
I really got to say, finally getting friends saying it is a cool phone shows people's acceptance and awareness. I really glad Nokia makes such nice iconic phone and be an exclusive phone maker for WP platform. It really helped WP ecosystem a lot and I am grateful to it.
I am grateful for HTC and Samsung early supports, but, Nokia really turned the ecosystem around.
