You pretty much have three options when deciding on a smartphone. You can go with a tiny (4-inch) device like Apple's iPhone 5. Then there are several mid-sized phones with 4.5 to 5-inch displays like Samsung's Galaxy S4 or Nokia's Lumia 1020.
And then there are the phablets, the supersized phones with 5.5 to 6-inch screens. Samsung popularized phablets with its Galaxy Note line of devices two years ago. A lot of people, including me, laughed at the attempt.
But since then, my thinking has evolved along with the market's. Millions of people are buying phablets, and there's clearly a hunger for them.
