Windows Phone 7, the latest mobile operating system version from Redmond-based software giant Microsoft, was put on sale in a series of European and Asia-Pacific markets about ten days ago, and already managed to win the hearts of customers, some of the latest reports on the matter suggest.

Germany is among the countries that started selling smartphones running under Windows Phone 7 on October 22, with all carriers there making such handsets available for purchase for their users.

Ten days later, the first stock issues are reported, as pre-order and demand for these Windows phone 7 devices seem to have exceeded expectations.

German publication n-TV.de says (via WMPoweruser) that wireless carrier O2, which has the HTC HD7 smartphone available exclusively on its airwaves, has sold-out the entire stock, and that it is currently expecting more units from HTC.

According to rumors, the wireless carrier managed to move a number of around 80,000 HTC HD7 units since the official release, which seems pretty impressive.

However, it seems that the HTC HD7 is not the only Windows Phone 7 device to register high demand on the German market, and that other wireless carriers reported strong orders for their devices too.

Vodafone Germany already confirmed that HTC 7 Mozart and the Samsung Omnia 7 have seen pre-orders that “exceeded expectations,” and that it ordered increased quantities to satisfy its customers.

LG Optimus 7 has registered high demand too, smaller carrier E-plus reports. The company announced that it plans on increase its stock in mid-November.

All in all, it appears that Windows Phone 7 indeed managed to attract a lot of users on its side in the markets where it was already made available.

Undoubtedly, the fact that it was loaded on powerful mobile phones had something to do with this, but the operating system in itself look very appealing too, offering a new approach to mobile devices, when compared to what other OSes have to offer at the moment.
