When it comes to the vast and wide-ranging functionality that smartphones have these days, most of us will have different ideas about what's the most important to us personally, be it the fitness app you use when running, online banking software or even something as simple as Angry Birds or Candy Crush.
However, while most smartphones are seen as jacks-of-all-trades, it seems like Microsoft is readying itself for the release of a smartphone that is pitched at one demographic in particular – selfie enthusiasts.
The rumour comes from The Verge, which is believed to have had access to some insider information following Microsoft's annual internal meeting over the past few days.
It said that vice president of devices and services Stephen Elop presented a new selfie-focussed smartphone to employees at the event, believed to use the codename Superman, which should bring it in line with the rumours that we first heard back in April.
What makes it so special for taking selfies, though? Apparently it's all in the camera. Windows insiders said that the device will feature a 5MP front-facing camera, which will make it easy to strike the perfect pose when snapping a picture of yourself.
However, Microsoft is believed to working on more than just this selfie phone at the moment, which will be important for its big push with the Windows Phone 8.1 operating system.
Other reports have stated that a second new phone with the codename Tesla is in the works at the moment, with the device likely to be a thinner version of the popular Nokia Lumia 930.
And while the selfie phone is likely to be one that will appeal mostly to people at the budget end of the market, it seems that the Tesla device will come in at a higher entry point. This phone has been described, according to The Verge, as an affordable high-end device by Mr Elop.
