After using the 4.2-inch Sony Ericsson Xperia Arc S for about a year, I’m seriously thinking of upgrading to the new 5-inch wonder, Sony Xperia Z aka Sony C660X Yuga, because the screen is larger with LTE support.

The Sony Xperia Z was spotted recently at the CES 2013 in Las Vegas Convention Center and features 3G, 5-inch full HD Reality display with a resolution of 1080 pixels, Bluetooth 4.0, LTE, 13 MP camera, Wi-Fi, GPS, supports SDXC format cards (up to 128GB), dust and water resistant casing. It’s also rumored to have a 1.5GHz processor and 2GB RAM.
