(From top to bottom) A Blackberry Bold smartphone, a Samsung Galaxy Note phablet, and an Apple iPad 2 tablet are displayed in this illustration photo in Hong Kong January 3, 2013. The shift to the mainstream by phablets -- they're likely to account for nearly 20% of all smartphones in 2013, a doubling of market share over 2012 according to ABI Research, is driven by a shift in consumer habits around the globe, as users turn to devices with larger screens but which are more portable than tablets and can also be used to make and receive phone calls.
