On a Stock Android Phone (Nexus 5)..

• The sartphone website presents in no less than 4 different layouts / resolutions.
• Sometimes those are combined on the same page.
• Layout is left aligned, leaving a larger then expected right margin.
• You have two seperate 'menu' buttons, one for the Global Nav and One for Site Mail / Notifications.
• Links open in a new tab, even on smartphones.

The consistant shifting back and forth between layouts on a Smartphone is exceptionally jarring to people.
