Windows Phone 7 has “gone gold”. The term comes from the old, CD-ROM, days when software manufacturers would send a "gold” master CD to the duplication plant. In the case of Windows Phone it means that the phone manufacturers have been given the final version of the product to put into their handsets.
I’ve been using Windows Phone 7 for a while now and I love it. Going back to the iphone turns out to be hard work. Windows Phone is one of those clever interfaces that grows on you. The more you use it the more of these little touches that you notice, like the way that icons rotate when you change the screen orientation. And moving between programs using the back button is really easy. Microsoft have a really big mountain to climb with this new platform. But they have also made something rather special. With a bit of luck the phones themselves should not be long coming as well.
The whole Windows Phone team deserves immense respect for what they have achieved in such a short time. Kudos folks.
