Apple's iPhone 6 Plus has dominated phablet sales in the United States for the first quarter of the year. The phablet market as a whole is having a good year, with 21% of total smartphone sales are phone and tablets in one.

The first phablet from Cupertino bested all the others, which came in with a 44% share on overall phablet sales in the country. People got quite excited that they can now have an iPhone that has a bigger screen.

"Apple's overall sales dominated AT&T, Verizon and Sprint where iPhone represented 59%, 43% and 50% of smartphone sales, while Samsung dominated smartphone sales at T-Mobile with a share of 42%," Kantar reported.

Not so long ago, the late Apple boss Steve Jobs said that the company should never resort to creating phablets, and should keep manufacturing same-sized smartphones. Almost five years ago, the topic of "big phones" came up during a Q&A with jobs, to which he responded, "You can't get your hand around it... no one's going to buy that." Jobs even went on to call the bigger phones "Hummers."

iPhone sales took a dip after competitors such as Samsung released smartphones featuring larger screens, thus, signaling Cupertino to take the "phablet road," and it was indeed a smart decision.

Many iPhone fans thought they would never see an iPhone with a much bigger display, which can be one of the reasons the first phablet from Cupertino was met by much excitement after a long wait.

According to sources, the main reason for purchasing an Android or iOS phone is the size of the screen. Nowadays, smartphones are not just used to send text messages or call someone, but are also used as "mini-computers" for checking emails and even playing games, where the size of the screen is quite important.

But not all phablet manufacturers are getting great numbers, apparently. Microsoft is not getting that much attention with its line of phablets, the Windows Lumia. According to reports, the dip in phablet sales might have something to do with the company's operating system.
