Microsoft launches Windows Phone 7 in the U.S. today

Today is the start of a new era for Microsoft – it marks the day Windows Phone 7 becomes available in the U.S, and that people will start forgetting about its mixed mobile past. I’ll admit that I have a warm place in my heart for Windows Mobile.

The mobile operating system powered that vast majority of smartphones I’ve used in the past decade, starting with the Philips Nino back in 1999. Since then, a lot changed in the mobile phone market, and ever since the iPhone and Android phones hit store shelves, Windows Mobile became a niche player, mainly loved by hardcore geeks.

But Microsoft is now back with a vengeance, and their Windows Phone 7 devices look set to change things for good. The mobile operating system is launching today on AT&T and T-Mobile, and by the end of the year, there will be Windows Phone 7 devices on all major carriers.

Later this week, we’ll bring you a full review of one of the first Windows Phone 7 devices with a strong focus on travel – and whether this new operating system really is worthy entrant back into the market. In the meantime, check out the full lineup of Windows Phone 7 reviews at Engadget. To learn more about the various Windows Phone 7devices, head on over to Microsoft.com.
