Windows Phone 7 has some speed to it. From running apps to simply starting up your Windows Phone, the zip Windows Phone 7 has is a noticeable improvement over Windows Mobile. The 1ghz processor helps speed things along nicely.
While the HTC Surround's start-up speed isn't as fast as what we've seen with the HTC HD7 boot times, it's still very respectable. From pressing the power button to seeing the Start Screen is just a smidgen over thirty seconds.
