The Z1S has a striking premium design that's both distinctive and alluring. Its waterproof construction is a rare and interesting trait. Factor in the phone's excellent battery life and exceptional camera — with its underwater photo-capturing potential — and you've got an unusually compelling device with loads of attractive qualities.
The Z1S isn't going to be for everyone, though. Its display, while generally quite good, is less impressive than other HD screens on the market. It ships with a dated version of Android and no current guarantee as to if or when it'll be upgraded. And perhaps most significant, its design — dazzling as it may be — makes for a cold and boxy form that's awkward to hold.
So it ultimately comes down to you — and what you want in a mobile device. If comfort and ergonomics are your priorities, the Z1S probably isn't the best choice for you. If you want a sleek and premium product, though, and don't mind a bulky frame, the Xperia Z1S is an outstanding high-end smartphone I'd readily recommend.
