I agree, I think there was a certain amount of 'standing on the shoulders of giants' as well as 'standing on burning deck' which both helped things along. That said, they have managed their use of Windows Phone and their marketing well and I take my hat off to them.

What I have noticed is the Apple fanbois take an interest when they see I have a 920. They usually ask to look at it and then make a big show of criticising it's weight, to which I reply 'Yes, it is a real man's phone all right'.
