The phones and tablets of MWC 2013

Huawei Ascend P2BARCELONA, Spain--As usual, the Mobile World Congress trade show here was the scene of a number of smartphone and tablet announcements, both major and minor. Vendors including Nokia, Samsung, ZTE and Huawei used the event to show off new products. Among the more notable announcements were Nokia's 105 phone that will sell for around $20, ZTE's Open smartphone that runs Firefox's new operating system and NEC's Medias W hybrid phone/tablet that sports two 4.3-inch screens hinged together. In past years, MWC has been the scene of flagship smartphone announcements by some of the market's major players, but this year show attendees were treated to more oblique announcements, such as Hewlett-Packard's surprise embrace of Android in tablets and Samsung's replacement of bada with Tizen.
