At least there are two smartphones running Mozilla Mobile OS showed off at MWC 2013, One Touch Fire and by Alcatel and ZTE Open by ZTE. All devices are seem made for budget-friendly market with mid-range hardware such as 1 GHz CPU, 512MB of RAM, 3.5-inch display and 3.2mp main rear shooter on Alcatel Fire. Similar specs found also on ZTE's first Mozilla phone including 3.5-inch display, Bluetooth and WiFi connectivity.
Sure this is just the beginning and probably this just something like trial product, but who knows it will gain something good in the smartphone market or will end under the attack fo other species. More polish and more is one thing in every new things before its really ready and finally accepted by the market concerned.
