The testing process has covered its usability, battery life, network connectivity, and many other metrics to make Windows 7 as high quality operating system.

“I’m very excited to share with this blog community, that our Windows Phone engineering team has hit a very meaningful milestone; one that we’re calling technical preview. We are certainly not done yet – but the craftsmen (and women) of our team have signed off that our software is now ready for the hands-on everyday use of a broad set of consumers around the world – and we’re looking forward to their feedback in the coming weeks, so that we can finish the best Windows Phone release ever together.”
