Now in the states, the Sony Xperia Z1 Compact is available from the manufacturer's website
That means that both models share some tasty specs such as the 20.7MP rear-facing camera, the quad-core 2.2GHz Snapdragon 800 processor, the Adreno 330 GPU, and the 2GB of RAM. Both phones also share the 16GB of native storage, and the 64GB capacity microSD slot. Many have given the TRILUMINOS screen on the Sony Xperia Z1 Compact the edge against the screen on the larger model, saying that colors are not washed out on the 4.3 inch display as they are on the 5 inch glass.
The Sony Xperia Z1 Compact can now be purchased in the states, directly from the manufacturer's website. Available unlocked in white, pink and black, the handset can be purchased for $549.99. The phone is IP58 certified and can withstand submersion to 4.92 feet of water for as long as 30 minutes.
Here is a chance to buy what is truly a compact flagship phone, as opposed to the "mini" handsets that usually have specs that have been dropped down a few pegs.
