Hi guys, Just wanted to find out from 6 Plus owners, is the custom keyboard such as SwfitKey, Swype etc. usable on the 6 Plus? I would have thought it would be unusable and kinda redundant on this device seeing as the majority of people are having difficulty reaching the end of the screen on the 6+. The custom keyboard generally aims to speed up one-handed typing, so it defeats the purpose if you can't reach the other end of your screen with your fingers. :| Would appreciate some opinions. Thanks!
