Sony's iPhone 6 competitor, the Xperia Z3 Compact, is now available in the US. No carrier is offering the Xperia Z3 Compact as of yet, so your only option is to pick up the unlocked version of the handset directly from Sony's official online store in the US. The Xperia Z3 Compact costs $529.99, which is far lesser than the $649 iPhone 6. Available color options include white, black, orange, and green.
