Summary: The Xperia Z Ultra is a very fast, slim and capable smartphone, but too few apps take advantage of its almost-tablet screen, and its poor camera experience and high price makes it a hard sell to the average smartphone user.
Conclusion: The Xperia Z Ultra is definitely not a device that everyone should rush out and buy but it is an exceptionally useful and wonderfully executed device. Going back to a standard (5 inch) phone for every day use has really proved how good the Z Ultra is and I have found myself swapping back and forth from my phone to my iPad Mini mid-task on a number of occasions as one device or the other was better suited to the task in hand.
Xperia Z Ultra revealed: World's slimmest and fastest, and largest Full HD screen
12 February 2014
Excerpt: Entering alongside Sony's own Xperia Z smartphone the Xperia Z Ultra has been targeted to take on the likes of Samsung's Galaxy Note 2, the Xperia Z Ultra does have a few tricks up its sleeve that will set it apart from Samsung's own 'phablet'. Not only is the Xperia Z Ultra the slimmest smartphone with the largest Full-HD display (6.4 inches), dethroning the Ascend P6 from its throne.
Summary: Overall, I have quite fallen in love with the Sony Xperia Z Ultra. It’s a big phone that can do big things. As a daily driver, it’ll give you stellar performance, both in battery stamina and smartphone functions. And it’s such a looker as well. If this was a lady, she’d be EVERYTHING a man could ever want. Beauty, brains, a bit of brawn, and I guess she can cook well, too.
Conclusion: The Sony Z Ultra Google Play Edition carves out a rather unique place in the Google collection of devices. Here you've got an ideal middle-place between smartphone and tablet, edging a lot more in on the tablet side of things. In this device is the vision we had back at the dawn of small, transportable computers. The Z Ultra is not too big to fit in your (admittedly mega-sized) pocket, and it's not too small that you'd not consider it for a do-anything device on the go.
The Sony Z Ultra Google Play Edition is too big in size and price
17 December 2013
Summary: The Sony Z Ultra Google Play Edition's insanely large size and stratospheric price make the Nexus 5 and Note 3 better options for pure Android power.
Pros: The Sony Z Ultra Google Play Edition squeezes a stunningly bright, and colorful display, stock Android 4.4 KitKat, and a muscular processor into an extremely thin package. With sealed ports, the water-resistant Z Ultra needn't fear liquid or exposure to dirt and dust.
Cons: Even considering the Sony Z Ultra GPE’s carrier-unsubsidized status, $649 is an exorbitant amount to pay. The Z Ultra’s overblown size makes it unwieldy to operate and its camera is disappointing.
