We see how Apple's first phablet compares with its latest tablet. Tech companies have been blurring the lines between device categories for the past few years. Traditionally the lines have been most blurred between the tablet and laptop categories, as the arrival of Windows 8 spurred a wave of convertible 'all-in-one' devices.

However, thanks to the ongoing trend to create increasingly big screen 'phablet' handsets, the category definitions between what constitutes a smartphone and a tablet have also become blurred.

This is neatly demonstrated with the release of Apple's first phablet, the iPhone 6 Plus, which led many buyers to question whether they still needed to invest in a separate tablet.
