Microsoft: Windows Phone 7 is "most thoroughly tested mobile platform" ever released

Yesterday Microsoft's new mobile platform Windows Phone 7 hit the RTM milestone, and in the official announcement Microsoft was keen to stress how mush tested had gone into this new platform.

Here's what Terry Myerson, Corporate Vice President of Windows Phone Engineering, had to say:

Windows Phone 7 is the most thoroughly tested mobile platform Microsoft has ever released. We had nearly ten thousand devices running automated tests daily, over a half million hours of active self-hosting use, over three and a half million hours of stress test passes, and eight and a half million hours of fully automated test passes. We’ve had thousands of independent software vendors and early adopters testing our software and giving us great feedback. We are ready.

That's a lot of testing ... but will it be enough?
