The iPhone 6 Plus is essentially a larger version of the iPhone 6 though it does come with some noticeable differences beyond its larger 5.5-inch display size.
Apple's largest iPhone ever comes with 1080p resolution, Optical Image Stabilization that cuts down on shaky video, and longer battery life. The size isn't going to be ideal for most people but those that want a larger smartphone display will probably fall in love with Apple's "phablet" iPhone option.
Of course, the size difference comes with an increased cost. While Verizon's iPhone 6 starts at $199.99, the Verizon iPhone 6 Plus starts at $299.99 on-contract. That's one of the more expensive on-contract price tags you'll face during the month of March and it means that you're going to need to be absolutely sure before you buy this phone.
