Being laser focused on productivity, Microsoft is perhaps in a better position than any of its rivals in the phone space when it comes the dreaded word: phablets. The $649 (about £422, AU$893) Lumia 950 XL has been touted as the ultimate phone for getting things done, but that boils down more to Windows 10 Mobile than the phone's size.Of course, the phone's dimensions certainly help. At 5.7 inches on the diagonal, this is definitely a two-hander handset for anyone that isn't The Mountain-sized or has unnaturally large mitts.Thankfully, Microsoft has made ample use of the enlarged screen size, using the extra room inside for some power-packed hardware, one way to ensure you get the most out of it and a neat method for keeping it all from burning up.Design and displaySave for a slightly different rear camera housing, the Lumia 950 XL looks nigh identical to its smaller sibling, the Lumia 950. The same matte white or black, polycarbonate (i.e. fancy plastic) shell is still here, along with the same array of volume, lock and camera shutter buttons along the right edge of the device. The bottom edge houses the same USB-C port as the 950.  Hands-on review: Microsoft Lumia 950 XL
