Just bought the Sony Z Ultra Google Play Edition from expansys for $335.
Definitely a niche device, here is a quick list of pros/cons after owning the device for <24 hours:
PROS:
6.4" screen, wonderful display, easy on the eyes.
Top notch fit and finish, the phone is all glass and metal.
Very clear call volume, even with people who I previous thought just had shitty phones. This is relative to the Nexus 5 call volume, my previous phone.
Everything is super fast, as really all phones should be these days.
Micro SD slot can hold a 64gb card.
Phone is water resistant, if you are in to that
Power input is at the top left corner of the phone, instead of the bottom. I like this for some reason.
Standby/power switch is on the middle right of the phone, and is a round, silver metal button. Much better to put the switch here instead of the top right on a phone this size. Volume rocker is right below the power switch.
Remarkably thin for a phone of this size
GPE so you will always get the latest android update (running 4.4.4 right now)
CONS:
The phone is enormous. Fits fine in dress slacks and shorts pockets, but I imagine it won't work with jeans.
All glass/metal design and the phones thinness could make it very easy to drop.
Little flaps over all the inputs due to the water resistant nature of the phone, except the headphone jack which is somehow still water resistant
A bit hefty weight wise, but this also adds to the solid feel of the phone.
Your significant other and friends will make fun of you and your enormous phone. But they are just jealous.
Camera doesn't have flash, but flash always ruins pictures for me anyway. Haven't had the opportunity to test the camera so I can't comment on overall quality.
