Sony better ccompete with Samsung that is mid end high end low end belongs to Chinese oem nd Indian OEM.
This Mediatek processor are as much as powerful as 1.2 Ghz quad core Snapdragon 400 ..but it does not support some games like Frontline commando . but don't think this is a bad one..
Merdiatek track record may be a concern, but provided Merdiatek is true to their claims and they really want to embrace the community, then the real game changer will be when Cyanogenmod starts to (officially) support the Merdiatek SoCs.
Companies like Micromax is moving towards Snapdragon and Sony towards MediaTek...thats a nice one...
