When we reviewed Sony's Xperia Z1 Compact, we concluded that it's exactly what a miniature flagship should be: big features in a small package. But despite the handset's many merits, Sony hasn't so far managed to offer it through any carriers in the US. Instead, starting today, it's selling the Z1 Compact direct from its own webiste, for a price of $550. The device is unlocked, of course, so at least you get the choice of whichever GSM carrier takes your fancy -- although its LTE bands don't make it especially friendly with AT&T.
