Samsung is launching the Omnia M, a new Windows Phone 7-based device, in Europe. The Windows Phone 7.5-equipped handset ships with a 4-inch Super AMOLED display and 1GHz processor. The device features a minimalist design with rounded edges and a curved back. According to Samsung, the case was designed ergonomically so it \"sits comfortably in your hand.\" The real focus of the Omnia M is its social features, which include access to the company\'s Family Story, a cloud-based network for family members to share messages, videos, and photos. Samsung has also bundled its ChatON service with the device, allowing users to engage in group chatting and messaging across several platforms, including iOS and Android. It\'s been a busy week for Samsung\'s Windows Phone business. Earlier this week, the company unveiled the Samsung Focus 2, a $50 Windows Phone boasting a 4-inch Super AMOLED display and 4G LTE support. That device is going on sale May 20 on AT&T\'s network. The Omnia M, on the other hand, will be coming to Europe first. Samsung said today that it plans to roll out the Omnia M to other regions, but didn\'t say when it\'ll start doing so.
