I've never been much of a fan of oversized phones -- pocket tumors, I call them -- but in Asia, phablets are already big and getting bigger by the day. Samsung has sold more than 30 million of its Galaxy Note "phablets" through two iterations of the device. A third, the Galaxy Note 3, could come this year.

Samsung could have more company by then. A leaked photo attributed to a Sony (NYSE:SNE) manufacturing operation suggest the consumer electronics giant is aiming to build a 6.44-inch touchscreen phablet. Huawei, meanwhile, introduced its own entry into the market at CES -- the 6.1-inch Ascend Mate.

So far, Apple (NASDAQ:AAPL) has resisted temptations to go into the super-sized phone market. Don't expect that to change, either:  CEO Tim Cook, like Steve Jobs before him, has never shown much interest in hybrid devices.

Is he right this time, too? Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova says Apple isn't well-positioned to build a phablet, but one of its main rivals might be.
