What we're about to describe is the same kind of phenomenon we experienced with 5-inch phones in 2010. If you recall, that year marked the debut of the Dell Streak 5, an absolutely massive smartphone / tablet hybrid for that time. 

The Xperia Z Ultra is Sony's first foray in the so-called “phablet” realm, and it comes with a bang, confirming everything we hoped for since the first Sony Togari rumors broke out. The goalposts are always moving in this category, but in general it constitutes of phones with really, and we mean really, big displays. Sony Xperia Z Ultra undoubtedly delivers in that respect, as it's the phone with the largest screen ever concocted, while still being called a handset... of sorts.
