The wrapping for responsive design uses too much space for the top half of the screen on a mobile phone.
Have a look at Good TV and/or the Xero mobile login as both use little space in the top bar.
The company name in green (in my case 'Swiftpoint' is redundant as it shows in the tab .. or if you only have one company then surely you must already know the company name. This would clear away space for the mobile phone and make much better use of screen display area and would also be helpful on the desktop version.
Finally, the front end has been replaced with an much more mobile-friendly UI.
