Late last night, a rather significant update went out for the OneDrive app for Windows Phone. With the app refresh came some highly requested features like support for OneDrive for Business. However, there was also a rather large UI change too, stirring some controversy amongst loyal Windows Phone fans.

Changes in app design are always a mixed bag. UI design is an art and like art, there are champions and critics for choices and layout. Some are rational others are pragmatic, and many are just subjective opinions.

Perhaps the most controversial design choice is the addition of the so-called 'hamburger button', something that even Windows Central uses on the website. These triple-line buttons are more common these days across UI design to designate menus, although they are relatively new to Windows Phone.

Putting aside ideological adherence to undefined 'Metro' principals, what do you think of the new design? Do you find it easier to access different parts of OneDrive and does the app make sense when you first look at it? Alternatively, does the new design stir confusion and revulsion at the idea that OneDrive is looking similar to Android and iOS?
